Trivia: Heavy metal pioneer Ozzy Osbourne first gained exposure as co-founder and vocalist of the groundbreaking hard rock band Black Sabbath, which formed in 1969 in Osbourne's hometown of Birmingham, England. After nearly a decade of helping to define the parameters of the heavy metal genre, Osbourne embarked upon a solo career that brought him even more success and infamy. He became a symbol for hard rock excess and outrageousness, thanks to his music's quasi-Satanic imagery, his very public substance abuse, and an assortment of bizarre stunts (such as biting the head off of a dove in front of a roomful of record executives and an arrest for urinating against the Alamo). Osbourne's few silver screen appearances have been cameos in youth-oriented films that play off his image as the ultimate rock & roll heathen, though his interview segment in the documentary The Decline of Western Civilization 2: The Metal Years was one of the few down-to-earth, honest moments in a revealing, and often damning, portrayal of the metal scene's fans and performers. However, it was with the 2002 premiere of the MTV reality series The Osbournes that Ozzy entered the strangest chapter of his career in the public eye. Millions tuned in weekly to peer into the day-to-day life of the Osbourne clan, as captured by a camera crew set up in the family mansion. Ozzy was revealed to be a sweet (if addled) husband and father who loved his wife and children despite the unending chaos and profanity that distinguished their home. The popularity of the series made Osbourne (and the rest of his brood) more famous than ever with many viewers who had never even heard his music. Along with wife Sharon, Ozzy became a symbol of modern parenting for some, and proof of American society's utter dysfunction to others. What's certain is that The Osbournes humanized the long-reviled singer's image and brought Ozzy mainstream television fame that no one could have ever predicted. Over the course of the next decade, Sharon became a celebrity in her own right by spouting off opinions on The Talk and insults on America's Got Talent, and Ozzy continued to rock fans all over the world in addition to being the subject of the 2011 documentary God Bless Ozzy Osburne -- a candid documentary that's guaranteed to make fans of The Osbourne's look back at the groundbreaking reality series in a diferent light. Ozzy continued to make music, reuniting with Black Sabbath in 2012 and working on his solo career.

Trivia: Gene Simmons is best known as the co-founder and arguable leader of the rock band Kiss (he's the one who wears the "demon" makeup and spits blood on-stage, among other antics). After the band became popular in the late '70s, Simmons embarked upon a relatively short-lived acting career that began with the made-for-TV movie Kiss Meets the Phantom of the Park (1978). He made his solo acting debut as a villain in Never Too Young to Die (1986). He went on to play villains in more films until his acting began interfering with his music. Simmons was born Chaim Witz in Israel but was raised in the U.S. After graduating from college, he spent a few months teaching sixth grade, but then left to become a musician.

Trivia: No stranger to emotionally and psychologically challenging roles, Doug Savant broke through the fear barrier that separates many actors from achieving their full onscreen potential. In the process, he tackled many characterizations somewhat removed from himself. These included a sociopathic rapist (in the 1995 TV movie Fight for Justice: The Nancy Cohn Story), a gay social worker (Matt Fielding on the prime-time soap opera Melrose Place), and -- most prominently -- a businessman-turned-stay at home dad (Tom Scavo, on the domestic black comedy Desperate Housewives). The latter, of course, required less of a stretch for Savant; it was perhaps ironic, then, that the Scavo characterization (opposite actress Felicity Huffman) reeled in Savant's largest audience and virtually turned him into a household name. Savant's resumé also includes brief appearances in such features as Secret Admirer (1985), Teen Wolf (1985), The Hanoi Hilton (1987), and Godzilla (1998). His second wife is actress Laura Leighton, whom he met on the set of Melrose.

Trivia: Alice Nunn was a character actress who enjoyed a 24-year career on-stage, in movies, and on television. Born in Jacksonville, FL, in 1927, she was bitten by the performing bug early in life; she was in school productions of such works as My Sister Eileen and attended the Wesleyan Conservatory and School of Fine Arts. Nunn later trained at the American Theater Wing and worked in radio as a continuity director before getting her break in New Faces of 1956. A singing comedienne who resembled a young Pert Kelton crossed with Sheila James, Nunn worked on-stage with Shelley Berman and Nancy Walker, and made her screen debut on television in episodes of Petticoat Junction. She later became a regular denizen of '60s sitcoms, playing comically strong-willed, often slightly belligerent women. Fans of 1960s sitcoms may remember her from Camp Runamuck as Mahala May Gruenecker, the head counselor of Camp Divine and the nemesis of series star Arch Johnson's Commander Wivenhoe; she was the perfect foil to Johnson's hulking macho boys camp leader, locking horns with him every week in much the same way that Margaret Rutherford had with Alastair Sim in the movie The Happiest Days of Your Life. Nunn's first feature film was Johnny Got His Gun (1971), in which she was one of the nurses. She was also a regular cast member of the Tony Orlando and Dawn variety show, but many of her film roles were bits, such as "Fat Lady" in Mame (1974) and "Passenger with Dog" in Airport 1975. She occasionally got bigger roles, such as the put-upon servant Helga in Mommie Dearest (1981), and is probably best remembered by 1980s filmgoers and Tim Burton fans for her portrayal of "Large Marge," the lady truck driver who frightens the hero in Pee-Wee's Big Adventure (1985). If Nunn hadn't been so good at comedy, and exploiting the funny side of her imposing girth and presence, she might have been an older rival to Shirley Stoler, but it was not to be -- she died of heart failure in the summer of 1988, at age 60.

Trivia: Fuzzy-faced actor Charles Martin Smith took time off from his studies at Cal State to make his cinema debut in The Culpepper Cattle Company (1972). Specializing in nerdish, owl-eyed teenagers during the early stages of his career, Smith scored a hit as Terry "The Toad" Field in the two American Graffiti movies of the mid-1970s. He was afforded a rare star part as real-life Canadian author Farley Mowat in Never Cry Wolf (1983), delivering what amounted to a one-man show as he braved the treacherous Arctic to study the so-called predatory behavior of wolves. Other Smith performances worth noting include ill-fated FBI accountant Oscar Wallace in The Untouchables (1987) and AIDS researcher Henry Jaffe in the made-for-TV And the Band Played On. Turning director with the sloppy but endearing "horror musical" Trick or Treat (1986), Charles Martin Smith has gone on to man the megaphone on the love-'em-or-hate-'em comedies Boris and Natasha (1992) and Fifty/Fifty (1993).

Trivia: Dancer/actor Tony Fields launched his career as a charter member of the Solid Gold Dancers that wowed audiences during the early '80s on the television music hits show Solid Gold. He went on to dance in music videos, like Thriller, for Michael Jackson. He occasionally appeared in feature films such as Body Heat (1981), A Chorus Line (1985), and The Doctor. He also made a few guest appearances on television series like Murder, She Wrote, L.A. Law, and Santa Barbara.

Trivia: Supporting actor, onscreen from the '70s.
