Trivia: It would be difficult to land a more preternatural start to acting than American Cole Sprouse. An identical twin, the fair-haired Cole reportedly commenced television appearances as early as six months old, when he and brother Dylan were jointly cast as Patrick Kelly, the eight-month-old son of acid-mouthed oil-refinery worker Grace Kelly (Brett Butler) in the popular ABC sitcom Grace Under Fire. After that program's cancellation in 1998, the Sprouses signed to appear opposite funnyman Adam Sandler in his 1999 comedy Big Daddy, directed by Dennis Dugan. In that vehicle, the then-five-year-old twins play Julian, a little boy adopted by misfit and loser Sonny Koufax (Sandler), who hopes to prove to his estranged girlfriend that he's capable of juggling "adult" responsibilities.As they aged, the twins branched out into separate roles and careers. The divergence began around 2000, when Cole Sprouse signed (sans his other half) to play Ben, the school-age son of Ross Geller (David Schwimmer), in several episodes of the blockbuster sitcom Friends. In 2001, the Sprouses reunited onscreen (and re-teamed with Adam Sandler) to voice the K-B Toys Soldiers in Sandler's animated holiday comedy Adam Sandler's Eight Crazy Nights. From this point on, the Sprouses typically appeared together (as -- surprise -- brothers!) in lieu of playing the same role interchangeably. For example, they portrayed soccer-playing twins in the family-friendly 2003 comedy Just 4 Kicks, directed by Farrelly Brothers collaborator Sidney Bartholomew Jr. The brothers hit a zenith of sorts with their 2005 sitcom The Suite Life of Zack and Cody, in which they play a couple of wiseacre twins who reside in a Beantown hotel and wreak all sorts of havoc there. Bit roles in Hannah Montana, Wizards of Waverly Place, and Wizards on Deck with Hannah Montana followed after The Suite Life with Zack and Cody went off the air in 2008, and after reteaming with Dylan for The Suite Life on Deck that same year, the siblings stuck together for The Suite Life Movie in 2011.

Trivia: Along with his twin brother, Cole, the fair-haired Dylan Sprouse reportedly commenced television appearances as early as six months old, when the two boys were cast as Patrick Kelly, the eight-month-old son of acid-mouthed oil-refinery worker Grace Kelly (Brett Butler) in the popular ABC sitcom Grace Under Fire. After that program's cancellation in 1998, the Sprouses signed to appear opposite funnyman Adam Sandler in his 1999 comedy Big Daddy, directed by Dennis Dugan.

In 2001, the Sprouses reunited onscreen (and re-teamed with Adam Sandler) to voice the K-B Toys Soldiers in Sandler's dreadful animated holiday comedy Adam Sandler's Eight Crazy Nights. From this point on, the Sprouses typically appeared together (as -- surprise -- brothers!) in lieu of playing the same role interchangeably. For example, they portrayed soccer-playing twins in the family-friendly 2003 comedy Just 4 Kicks, directed by Farrelly Brothers collaborator Sidney Bartholomew Jr. The brothers hit a zenith of sorts with their 2005 Disney Channel sitcom The Suite Life of Zack and Cody, in which they play a couple of wiseacre twins who reside in a Beantown hotel and wreak all sorts of havoc there.

Trivia: An actress from the age of six, Brenda Song first achieved pronounced fame in her teens, by virtue of frequent work in Disney Channel productions. Born in 1988 to a Thai-American mother and a Hmong father, Song landed one of her earliest screen assignments in 1996, with a small part in the Hulk Hogan comedy Santa With Muscles, then appeared in the following year's big-screen comedy Leave It to Beaver. Scattered assignments in television series followed, including Judging Amy, 7th Heaven, and The Bernie Mac Show, and Song son graduated to Disney Chanel work at age 12, with parts in that station's cable telemovies The Ultimate Christmas Present (2000) and Get a Clue (2002). She broke through to her widest audience, however (and maintained a much higher profile) when she starred opposite the Sprouse twins, Dylan and Cole on the Disney Channel sitcom The Suite Life of Zack and Cody (2005). On that series, Song plays London Tipton, the spoiled-rotten daughter of the owner of the hotel where the titular youngsters reside. Song then had an opportunity to show off her interest in tae-kwan-do as the title character in the martial arts extravaganza Wendy Wu: Homecoming Warrior (2006) and tackled a supporting role opposite Raven-Symone and Martin Lawrence in the road comedy College Road Trip (2008).
