Trivia: Identical twin Tamera Mowry starred as Tamera Campbell, opposite her sibling Tia, on the popular sitcom Sister, Sister -- both in its original ABC Friday-night run and later during its four-year stint on the WB network. This stardom arrived at the tail end of several one-shot prime-time series appearances and commercial appearances that began during the actress' preteen years. During the Sister, Sister period and for years afterward, the Mowrys broke the mold of standard twin and triplet actors by appearing together in films and television programs, in lieu of forking off into different paths. They co-headlined the family-oriented comedy Seventeen Again (2000), the teen movie The Hot Chick (2002), and the 2005 Disney Channel telemovie Twitches (a kind of rehash of the Sister, Sister premise with an occult twist, which spawned a sequel in 2007), but also essayed individual roles from time to time. Circa 2000, Tamera struck out on her own, starring in the Billy Graham-produced Christian telemovie Something to Sing About, alongside Graham, Darius McCrary, Kirk Franklin, and Irma P. Hall. She also joined the cast of the popular Lifetime medical drama Strong Medicine during that show's fifth and sixth seasons, as Kayla Thornton, a young physician from a rural area who arrives as a first-year resident at Philadelphia's Rittenhouse Women's Health Clinic following the traumatizing death of her brother, with the intention of pursuing a medical career. In later years, Mowry branched out more into reality TV, including a show with her sister Tia (cleverly titled Tia & Tamera), but still occasionally returned to acting.

Trivia: Gen Y-ers will doubtless remember Tia Mowry as Tia Landry, one of the long-estranged, suddenly reunited titular siblings on ABC's Friday night "TGIF" sitcom Sister, Sister -- a role Tia played opposite her identical twin, Tamera, from 1994-1995, and carried over into an extended run on the then-fledgling WB network from 1995-1999. Though this hardly constituted the actress' premier role (she had already essayed a sequence of guest appearances on various U.S. series during her early teenage years), it did generate substantial audience attention and paved the way for additional onscreen work. Whereas many other multiple-birth actresses and actors (for instance, the Olsen Twins and the Sprouse Twins) first tackled projects that called for twin roles, then forked off into divergent paths, the Mowrys cut back and forth between joint casting and separate casting. They co-headlined the family-oriented comedy Seventeen Again (2000), the teen movie The Hot Chick (2002), and the 2005 Disney Channel telemovie Twitches (a kind of rehash of the Sister, Sister premise, with an occult twist), but essayed individual roles from time to time. Tia provided one of the main voices for the 2005 animated musical Bratz: Rock Angelz (and the accompanying Bratz TV series); she also signed for the lead in the sitcom The Game (2006), as Melanie Barnett, a med student who transfers from John Hopkins to a small San Diego college to be near her professional football player boyfriend. A spin-off of the CW hit Girlfriends, The Game was still going strong in 2012.

Trivia: A recording sensation with young R&B fans, Los Angeles native Marques Houston attained superstardom in late childhood by joining the pop-rap ensemble Immature, alongside Jerome Jones and Kelton Kessee. (Houston was only 11 in 1992, when the group put out its first release). Houston got his first taste of Hollywood stardom by voicing one of the characters in the urban-themed animated feature Bebe's Kids (1992) and by making an on-camera appearance alongside his bandmates in the 1994 urban comedy House Party 3 (starring Kid 'N Play). The band then renamed itself IMx in the mid-'90s. As its members continued releasing albums, Houston moved onto film roles while recording on the side. Projects included episodes of the ABC sitcom Sister, Sister, a turn as Elgin in the teen-oriented dance film You Got Served (2004), and a role as Dumb Donald in the family-friendly comedy Fat Albert (2004). In 2007, Houston switched genres and essayed one of his first lead roles in a feature as one of several teens who fall prey to the homicidal inclinations of an unseen menace in the slasher outing Somebody Help Me (2007).
