Mark Ruffalo, 'Reservation Road'

What Mark Ruffalo does in 'Reservation Road' would not sit well with the rest of his superhero co-stars. In the film, he plays a father who hits a young boy with his car and subsequently tries to cover up the accident. Jeez, someone sick the Hulk on this guy. (Ruffalo also went dark as a cop in 'In the Cut.')
