Trivia: Perky, red-haired actress Bonnie Franklin is best remembered for playing plucky single mom Ann Romano on the long-running sitcom One Day at a Time (1975-1984). Franklin began her acting career at age 12 when she appeared in the Alfred Hitchcock made-for-television movie The Wrong Man in 1956; that year she also appeared in a feature-film episode of the Kettle family saga, The Kettles in the Ozarks. Through the '60s, Franklin only appeared a couple of times as a guest star on television series such as The Man from U.N.C.L.E. While working on her sitcom, Franklin occasionally appeared in television movies. After the series' demise, her television work became sporadic, and by the early '90s, she had left the medium altogether, though Franklin continued acting in regional theater and in cross-country tours of plays, occasionally returning to the screen for small appearances. Franklin reuinted with her One Day at a Time daughter Valerie Bertinelli in an episode of Hot in Cleveland in 2011, but her return to acting was short-lived. After announcing she had pancreatic cancer in 2012, Franklin passed away due to complications from the disease in 2013 at the age of 69.

Trivia: MacKenzie Phillips is the daughter of "The Mamas & the Papas" lead singer John Phillips, the stepdaughter of actress Michelle Phillips,and the half-sister of another film performer, Chynna Phillips. MacKenzie was 13 years old when she essayed her first film role as underaged "cruiser" Carol in American Graffiti (1973). She then essayed a series of juvenile-delinquent TV guest spots, which ended in 1975 upon her being cast as Julie Cooper on the popular sitcom One Day at a Time. During the run of this series, MacKenzie accepted a few outside assignments, notably a cameo as Lillian Gish (whom she closely resembled) in the made-for-TV The Silent Lovers (1980). Drug problems and run-ins with the law compromised MacKenzie's ability to function on One Day at a Time, culminating in her being fired during the 1979-80 season. After going "cold turkey," MacKenzie Phillips briefly returned to the series in 1981, but her previous self-destructive lifestyle had taken its toll on her physical and emotional makeup; she left One Day for good in 1983, and has worked but little since.

Trivia: During her nine-year (1975-1984) tenure as Barbara Cooper on TV's One Day at a Time, Valerie Bertinelli grew from a chubby, awkward 15-year-old with only a smattering of bit-part credits into a polished actress and bona fide sex symbol. When Bertinelli "married" her One Day co-star Boyd Gaines in a 1982 episode, the ratings went through the roof, while many a male viewer's heart sank. One year earlier, Bertinelli had been a bride for real; her marriage to rock star Eddie Van Halen was kept under wraps by the series' producers for fear of damaging the actress' "Little Miss Perfect" image. Bertinelli's son by Van Halen was named Wolfgang, as in Mozart. While still a One Day regular, Bertinelli made the first of many TV-movie starring appearances in 1979's Young Love, First Love; later small-screen projects -- most of them packaged by Bertinelli's own production company, Bertinelli Inc. -- included The Princess and the Cabbie (1981), I Was a Mail Order Bride (1982), Shattered Vows (1984), The Seduction of Gina (1984), Silent Witness (1985), and Pancho Barnes (1988). Conversely, her theatrical-feature credits are limited, but include C.H.O.M.P.S. (1979) and Ordinary Heroes (1985). In the years since One Day at a Time, Valerie Bertinelli has starred in the short-lived TV series, Sydney (1990) and Café Americain (1993).At the beginning of the 2000s, she landed a recurring role on Touched By an Angel. In 2005 she filed for divorce from Eddie Van Halen, and a few years later she would be the star of yet another series, the TV Land sitcom Hot In Cleveland opposite Wendy Malick, Jane Leeves, and Betty White.

Trivia: A graduate of NYU, American actor Richard Masur has been seen in supporting TV and movie roles since the early 1970s. His pliable facial features, boyish demeanor and indeterminate age have enabled Masur to play a rich variety of roles: a mentally retarded stockboy on All in the Family, a hotshot program manager on The Mary Tyler Moore Show, and even a "friendly stranger" child molester in the 1981 TV movie Fallen Angel. Masur's film credits include Semi-Tough (1977); Who'll Stop the Rain (1978); My Girl (1991), as Jamie Lee Curtis' prickly ex-husband; and the deservedly maligned Heaven's Gate (1980). Masur has also been a regular on several TV series: From 1975 through 1976, for example, he was divorcee Bonnie Franklin's much-younger boyfriend (and almost her second husband) on One Day at a Time. In 1987, Masur made his film directorial bow with the Oscar-nominated short subject Love Struck, but he continues to work primarily as an actor in both TV and film.
