David Dastmalchian is used to making the most of a small role. His first feature-film appearance was in 2008’s The Dark Knight as Thomas Schiff, one of the Joker’s henchmen in the film’s taut assassination scene. You remember — he’s the guy captured by Gotham police and interrogated by Harvey Dent in the ambulance. With little more than a deranged giggle and a sweaty, darting glance, Dastmalchian created a career.
