Trivia: Best remembered for his high-profile acting roles on two 1970s television sitcoms -- that of genial news writer Murray Slaughter on CBS's The Mary Tyler Moore Show (1970-1977) and that of sweet-natured Captain Merrill Stubing on ABC's The Love Boat (1977-1986), stage-trained actor Gavin MacLeod in fact began his career typecast as a villain. He landed parts in Hollywood features including The Sand Pebbles (1966), Deathwatch (1966), and The Comic (1969), and enjoyed a tenure as Joseph "Happy" Haines on the sitcom McHale's Navy from 1962 through 1964. After The Love Boat permanently laid anchor in the mid-'80s, MacLeod signed on as a spokesperson and pitchman for Princess Cruises and returned to regional theatrical work. He also tackled guest spots on programs including Touched by an Angel and (in a move that surprised everyone) the HBO prison drama Oz. Off-camera, MacLeod is an outspoken born-again Christian. He hosted a popular talk show on the Trinity Broadcasting Network, along with his wife, Patti (whom he divorced in 1982 and remarried three years later), called Back on Course, and personally funded many of the Greatest Adventure Stories from the Bible animated videos for children.

Trivia: Universally recognized as Ship's Doctor Adam Bricker on the blockbuster prime-time sitcom The Love Boat (1977-1986) -- a part he held for the entire nine-season run of the series -- actor Bernie Kopell entered the doors of show business via a most unlikely route. Born in Brooklyn, Kopell attended Erasmus High and then New York University (with a dramatic art major). After a stint at sea aboard the naval vessel USS Iowa, Kopell signed on to drive a taxicab in Southern California -- and achieved his big break on the day that Oregon Trail (1959) film producer Dick Einfeld hitched a ride in the back of his cab. In a span of minutes, Kopell reportedly managed to convince Einfeld that he was not really a cab driver but an actor in serious need of work. The effort paid off, and Kopell snagged his first part -- a two-line part in Oregon as an aide to president James K. Polk. In the early '60s, Kopell joined the Actors' Ring Theatre in Los Angeles, where he developed a knack for characterizations and voices; this led, in turn, to character-type roles on a myriad of television programs including The Dick Van Dyke Show, The Steve Allen Show, and My Favorite Martian (which often, though not always, cast the wiry Kopell as a Hispanic). By the early '70s, Kopell had landed steady assignments on Get Smart, Bewitched, That Girl, and other series. The Love Boat, however, embodied his breakthrough. He followed it up with an emcee assignment on The Travel Channel (hosting its Railway Adventures Across Europe) and a surge in theatrical work, with portrayals in regional productions of such plays as Rumors, A History of Shadows, and Death of a Salesman.

Trivia: Actor Fred Grandy enjoyed two distinct careers -- an initial career as an actor and a proverbial second wind on the political stage. As a thespian, Grandy signed for guest spots on early-'70s series including Maude and Phyllis, but built his reputation via his nine-season portrayal of Yeoman-Purser Burl "Gopher" Smith, right-hand man to Captain Merrill Stubing (Gavin MacLeod), on the popular television sitcom The Love Boat (1977-1986). He proved popular with audiences, but by the mid-'80s reportedly grew tired of acting and gravitated to the political arena because he found it more challenging. Indeed, in 1986 -- the year of Boat's cancelation -- Grandy was elected as a Republican member of the House of Representatives from Iowa.

Trivia: For millions of Americans, the prime-time situation comedy The Love Boat will be forever inseparable from the image of Ted Lange, an actor cast for nine seasons as the genial Isaac the Bartender on the Pacific Princess luxury liner and trademarked by his iconic "two-finger drop" greeting. Yet Lange's portrayal of Isaac scarcely hinted at the actor's dexterity or dramatic range. In truth, this actor received classical dramatic training at London's Royal Academy of Dramatic Arts, and would go on, after the Princess took its final voyage in September 1986, to establish himself as a revered creative force in regional theater.Lange initially broke into films with many portrayals in Hollywood programmers during the early '70s, including Trick Baby (1972), Blade (1972), and Black Belt Jones (1974), and landed a regular role in the one-season ethnic sitcom That's My Mama (1974), as a streetwise philosopher opposite Clifton Davis (Amen) and Theresa Merritt. The Love Boat, of course, brought Lange his most widespread recognition; nonetheless (as indicated), he hearkened back to his theatrical roots beginning in the late '80s and divided his time between writing, directing, and stage acting roles. His resumé as a scribe sports at least 17 original plays including Lemon Meringue Facade, Behind the Mask -- An Evening with Paul Laurence Dunbar, and Evil Legacy -- The Story of Lucretia Borgia, while he has appeared dramatically in productions including Hair and Taming of the Shrew and has directed plays ranging from Othello to the rock & roll musical Born a Unicorn.

Trivia: Jill Whelan enjoyed an acting career as a child star, with a seven-season (1979-1986) portrayal of Vicki, Captain Merrill Stubing's young daughter, on the prime-time ABC situation comedy The Love Boat. After the series wrapped in 1986, Whelan returned for a number of Love Boat telemovies, acted in regional theater, and played a regular role on the daytime soap opera The Young and the Restless. Astute movie buffs may remember Whelan for a brief but memorable big-screen contribution that happened during her Love Boat tenure: she also portrayed Lisa Davis, the ailing child sent into convulsions when a singing nun knocks out her I.V., in the Zucker-Abrams-Zucker farce Airplane! (1980).

Trivia: Served in the U.S. Army in Vietnam after graduating college. Was a non-celebrity competitor on The $10,000 Pyramid in 1974 and, after he became a star, appeared on the show a number of times. In 1990, made his Broadway-musical debut in City of Angels. Played Jeeves in the 1996 American premiere of the Andrew Lloyd Webber musical By Jeeves. Played the Wizard of Oz in a national tour of Wicked (2010). Runs the Richard Kline Acting Workshop. Has toured and made public appearances with his Three's Company costars Joyce DeWitt and Priscilla Barnes.

Trivia: Tall, blonde leading-lady Joan Van Ark began making the guest-appearance rounds in TV programs of the early 1970s. Her first regular nighttime series work was in the sitcoms Temperatures Rising (73) and We've Got Each Other (77). Though adept at comedy, Joan is better known for her soap-opera work, first as Janene Whitney on the daytimer Days of Our Lives, then as Valerie Ewing on the nighttime serial Dallas. One year after her first 1978 appearance as Valerie, Joan carried the character over into the spin-off series Knot's Landing, appearing in both series until 1981. Joan Van Ark remained with Knot's Landing almost up to its cancellation in 1993; when she left to do a pilot for a TV sitcom, the producers contrived to have her character blown up in a car, effectively preventing Ms. Van Ark from harboring second thoughts. A little-known aspect of Joan Van Ark's career is her extensive work as a cartoon voiceover actress, notably as the leading character in the Saturday morning animated series Spiderwoman (79).

Trivia: A classically-trained lead actor, Robert Reed appeared onscreen from 1958. His most famous role was as the father on the TV series The Brady Bunch.

Trivia: In films from 1965, American actor Alex Rocco specialized in tough-guy roles, sometimes leavening his hard-bitten portrayals with a dash of roguish humor. Rocco's film assignments included such parts as gangster Legs Diamond in St. Valentine's Day Massacre (1967) and Moe Greene in The Godfather (1974). He has been a regular or semi-regular on a number of television shows, beginning with 1975's Three for the Road, in which he starred as free-lance photographer (and full-time family man) Pete Karras. Alex Rocco has since been seen in such TVers as The Facts of Life as Mr. Polniaczek, Sibs as Howie Roscio, The Famous Teddy Z as Al Floss, and The George Carlin Show as Harry Rossetti. He played the father of Jennifer Lopez's character in The Wedding Planner (2001) and was a recurring character on the short-lived series Magic City (2012-13). Rocco died in 2015, at age 79.

Trivia: Actress Pat Klous began her career in the 1970s as a Manhattan-area model, and graduated to dramatics when tapped by CBS to star opposite fellow neophytes Connie Sellecca and Kathryn Witt in the prime-time adventure drama Flying High (1978-1979). The series told of three young women and their exploits stewardessing for the apocryphal Sunwest Airlines. It failed to take off, however, and folded about four months after it initially debuted. Ironically (or perhaps not so, given the networks' tendencies to emulate one another), the program bore more than a passing resemblance to The Love Boat, which had scored major ratings when it debuted a season prior on ABC -- so it seemed wholly fitting that Boat's producers tapped Klous to star in their thematically similar sitcom Aloha Paradise (1981) and then, a few years later, to replace Love Boat stalwart Lauren Tewes when Tewes was dropped from that program amid a serious cocaine addiction. On The Love Boat, Klous portrayed Cruise Director Judy McCoy. She remained with the program from 1984 until it folded in 1986, then did occasional television work thereafter.

Trivia: Dividing his time more or less equally between big- and small-screen work, actor Ted McGinley enjoyed a considerably successful tenure as a character player, almost always appearing as beefcake heartthrob types. He began his career in the early '80s, with small roles in Garry Marshall's satirical farce Young Doctors in Love (1982) and the lurid Joan Collins telemovie Making of a Male Model (1983), but achieved his first significant break in the sitcom venue, as English teacher-cum-basketball coach Roger Phillips on the final four seasons of Happy Days (1980-1984). Fortuitously, at about the same time that Days folded, the producers of The Love Boat (on the same network, ABC) tapped McGinley to play photographer Ace Evans -- a last-ditch attempt to save the program from sagging ratings. The strategy ultimately failed when Boat ended its lengthy run in 1986, but in the meantime, McGinley landed what became a recurring role as jock Stan in the first three installments of Revenge of the Nerds. Eventually, McGinley also joined the cast of the long-running Married...With Children from 1991 through 1997, playing chauvinistic layabout Jefferson D'Arcy (second husband of the Bundys' neighbor Marcy Rhoades), and essayed roles in theatrical films including Physical Evidence (1989), Wayne's World 2 (1993), and Dick (1999). The late '90s and 2000s found McGinley evincing a heightened presence in television once again, first on Aaron Sorkin's critically worshipped yet short-lived seriocomedy Sports Night (1998-1999), then as Charley Shanowski on the sitcom Hope & Faith (2003-2006). In 2008 he competed in the reality program Dancing With the Stars, and in 2010 he appeared in the lighthearted, family-friendly Christmas with a Capital C. He would reach pop-culture immortality when the website Jumping the Shark named him as one of the signs that a TV show has run out of ideas.
