David Dastmalchian (born in 1984) is an American actor known for film, television and theatre work. Originally from Kansas, he studied at The Theatre School at DePaul University. In Chicago, he received acclaim for lead roles in Tennessee Williams' The Glass Menagerie and Sam Shepard's Buried Child.
Dastmalchian's feature film debut was as the Joker’s deranged henchman, Thomas Schiff, in Christopher Nolan's movie The Dark Knight. His turn as Bob Taylor in Denis Villeneuve's Prisoners received strong reviews. Richard Corliss of Time called Dastmalchian's performance "excellent - chatty, modest with some subtle telltale psychopathy" and The Guardian's Paul MacInnes likened his introduction as a new suspect to Kevin Spacey's entrance in Seven.
In March 2014, Dastmalchian was awarded the Special Jury Prize for Courage in Storytelling at the South by Southwest Film Festival. He wrote and starred in the feature film Animals, directed by Collin Schiffli. Ashley Moreno of The Austin Chronicle credits Dastmalchian's screenplay with "present[ing] an authenticity often lacking in films about drug abuse." Film Threat's Brian Tallerico similarly sings the praises of Dastmalchian's breakout performance, noting his ability to "capture that sense of self-loathing that comes through in the body language of an addict without overselling it." 
Other feature film appearances include starring roles in the psychological thriller The Employer, the indie grindhouse hit Sushi Girl, the Detroit-based drama Cass (winner, San Diego Black Film Festival), Girls Will Be Girls 2012 (sequel to the cult hit, Girls Will Be Girls), Saving Lincoln and Virgin Alexander.
He has most recently been seen on television as Simon on the Fox sci-fi series Almost Human episode "Simon Says", as a chess expert and murder suspect on CSI: Crime Scene Investigation and as Oz Turner on the new BBC series Intruders. Other television appearances include the FX comedy The League, the new Showtime series Ray Donovan, and NBC's long-standing medical drama ER.
