In the midst of all this came WarGames, a fizzy little thriller about looming Armageddon. It's a deceptively simple story: High schooler David Lightman (played by 21-year-old Matthew Broderick) is a digitally proficient goofball who wants to play an unreleased computer game and impress a pretty girl (Ally Sheedy).
Ally Sheedy was a mostly unknown 20-year old when she was cast in WarGames. Coming off steady work in television and a pivotal, but relatively small role opposite Sean Penn in 1983's Bad Boys, Sheedy was cast opposite Matthew Broderick, in just his second film (following Max Dugan Returns).
