Kyle Gallner
In 2005, Gallner joined the cast of "Veronica Mars" for the last three episodes of the first season, giving him the opportunity to carry over his role of Beaver into the next season - a role which depicted him as a needy and emotionally neglected, but nonetheless nefarious perpetrator of a heinous bus crash, among other dastardly deeds. During his run on "Veronica Mars," Gallner continued making guest spots, appearing in episodes of "Jack & Bobby" (WB, 2004-05), "Cold Case" (CBS, 2003-10), "CSI: New York" (CBS, 2004-13) and "Bones" (FOX, 2005-). After the troubled and guilt-ridden Beaver committed suicide at the end of season two, Gallner began a recurring role as a devout Mormon trying to keep a polygamist's son (Douglas Smith) on the path to purity in the controversial HBO series, "Big Love" (2006-11). 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.
