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" (NBC, 1999-2005). After making his feature debut with a small role in the bizarre Michael Showalter comedy, "Wet Hot American Summer" (2001), he returned to television with episodes of "Law & Order: Special Victims Unit" (NBC, 1999- ) and "Touched By an Angel" (CBS, 1994-2003). He next appeared in the series finale of "The District" (CBS, 2000-04) before playing his first recognizable role - that of Bart Allen (a.k.a. "The Flash") on "Smallville" (CW, 2001- ) during the 2004-05 season.

Gallner began a recurring role as a devout Mormon in the controversial HBO series, "Big Love" (2006- ).
