Sam Witwer

Witwer was born on October 20, 1977, and grew up in Glenview, Illinois, a suburb north of Chicago. Ever since he was a child, Witwer showed enthusiasm in other pursuits he enjoyed more than school. He spent his free time huddled over a computer, playing Dungeons and Dragons, or making music.

He attended Glenbrook South High School, during which time he was involved in drama and theater classes, as well as being the lead singer of a high school band called "Love Plumber". After barely graduating high school, his parents made him apply to drama departments of various schools. Finally getting accepted to the Juilliard School. When he was 18 he became friends with fellow actor Glenn Howerton.

After 2 years at Juilliard, Witwer got kicked out from school as he didn't take it seriously enough. He finally made the decision to pursue acting after asking actor Bruce Campbell for advice on an online website called AOL.Witwer's first on-screen credit was that of a Chicago Bulls commercial. He soon found himself in speaking roles on hit television series, such as ER.

Witwer's first major recurring role came in the form of portraying raptor pilot 'Crashdown' (his call sign) on Battlestar Galactica, although he has credited much of his current success to his role as Neil Perry on the Showtime series Dexter.

From 2008 to 2009, Witwer was cast in season 8 of Smallville as Davis Bloome, a charming paramedic who struggles with a darkness within as he is the human camouflage of Doomsday. Witwer played Davis while Doomsday was played by stuntman Dario Delacio. Witwer's performance in Smallville was incredibly well-received, and he has stated that his experience on the show had opened more opportunities for him in the future of acting. Witwer’s contract gave him the option to return in season 9 as Zod, though he ultimately declined. Though he considered his time on the show enjoyable and was flattered by the offer to stay on, he passed on the role as he felt it would be difficult for both the characters and audience to accept.

Witwer made a cameo appearance in The Walking Dead as a dead zombie soldier in a tank in the season 1 episode "Days Gone Bye" which reunited him with director Frank Darabont from The Mist. Coincidentally, in 2019 he went on to portray the main protagonist (both voice and motion capture) of a video game called Days Gone, which also tackles the topic of zombie apocalypse.
