Kyle Gallner was born in West Chester, Pennsylvania. He started his career by following his sister along to one of her auditions. Perhaps best know for his role as Cassidy "Beaver" Casablancas on the CW's lone hit series, Veronica Mars (2004), actor Kyle Gallner had been appearing in films and on television since his early adolescence. Born on Oct. 22, 1986 and originally from Philadelphia, PA, Gallner made his first screen appearance on an episode of Third Watch (1999). After making his feature debut with a small role in Michael Showalter's bizarre comedy Wet Hot American Summer (2001) (2001), he returned to television with episodes of Law & Order: Special Victims Unit (1999) and Touched by an Angel (1994). He next appeared in the series finale of The District (2000) before playing his first recognizable role - that of Bart Allen (a.k.a. "The Flash") on Smallville (2001) during the 2004-05 season. In 2005, Gallner joined the cast of Veronica Mars (2004) for the last three episodes of the first season, giving him the opportunity to carry over his role of Beaver into the next season. During his run on "Veronica Mars," Gallner continued making guest spots, appearing in episodes of Jack & Bobby (2004), Cold Case (2003), CSI: NY (2004) and Bones (2005). Gallner began a recurring role as a devout Mormon in the controversial HBO series Big Love (2006). Meanwhile, Gallner revived his "Smallville" role in early 2007, returning as Impulse rather than The Flash - due to a feature film with the same character being developed by Warner Bros.
