William Castrogiovanni

Acting

Biography

Known for playing level-headed, whimsical, and spirited problem-solvers, William Castrogiovanni is the go-to geek for cult sci-fi and indie comedy productions. He's hacked into alien warships as the dogged Major Fry in "Independents' Day," plotted savage revenge as a pretentious author in "True Nightmares," and achieved perfect continuity as a meek script supervisor in "The Hollywouldn'ts." Next up, he will appear as a passionate economics professor in the comedy short "Demand Curve." William holds a BFA in Film and Television Production from NYU, has studied acting at UCLA and Playhouse West, and is a UCB and Second City LA Conservatory graduate.
