Giovanni Ribisi is the latest addition to Warner Bros’ ‘The Gangster Squad’ A period crime drama. Ribisi will play Conway Keeler, a cop in the group who is a master of electronics and wires. Now we talked about this before, this cast is turning out to be a star stacked. We should be in for a real treat with all these talented actors. Sean Penn, Mickey Cohen, Ryan Gosling just to name a few.
