Former Marine-turned-actor Adam Driver spends his spare time raising awareness about post-traumatic stress disorder (Ptsd) in the military by taking part in dramatic readings specially for members of the U.S. Armed Forces.

The Girls star enlisted in the Marines after high school, but he was honourably discharged two years later for a dislocated sternum.

However, Driver, 29, has continued to do his part to help veterans and active members of the military by teaming up with a friend who runs the touring Theater of War organisation and staging readings of Ancient Greek playwright Sophocles' war tragedies.

He tells Interview magazine, "My friend Bryan (Doerries) has a project where he does readings of selected scenes of Greek plays - Sophocles' Ajax and Philoctetes - for military audiences to spur a conversation about Ptsd. And I have this non-profit, Arts in the Armed Forces. We just had a big fundraiser.

"I do Bryan's project a lot, and he's on the board of our projects, and we trade resources. Ours is more contemporary - it's thought-provoking troop entertainment - and Bryan's is more of a social service...

"To feel like I can continue my service (in another way), that's always gratifying in the midst of all this seemingly crazy bulls**t (in Hollywood)... Working on things that start that conversation is pretty exciting."
