The great Samuel Fuller, made this crazed and memorable flick about a journalist, who is so obsessed with winning the Pulitzer Prize, he'll literally stare insanity in the face.
I saw this movie at Hunter College many years ago while taking a film class there and I loved it.
Mike D'Angelo of the A.V. Club writes:
Shock Corridor is the tale of an investigative reporter, Peter Breck, who goes undercover in an asylum in order to discover who committed a murder there some time earlier. Posing as an incestuous fetishist, he sells his phony psychosis to the staff while simultaneously cozying up to the crime’s three witnesses, all of whom are well off their respective rockers.
What interests Fuller is the variety of ways in which he can use the inmates to reflect the sickness of America’s soul. One witness was brainwashed by Communists and now believes himself to be a Confederate soldier. Another was so traumatized by his contribution to the atomic bomb that he’s regressed to early childhood. And the third…well, take a look for yourself.
