One bit of his work that illustrates that perfectly sticks in my head: a great episode of his 80s series that had a woman wrongfully sent to prison, and she gets the rough end of the stick all the way.
So the old guy who works in the morgue feels sorry for her and agrees that if she stows herself in the coffin with whatever body is prepared to go at midnight, she could be buried witht he body, and the morgue guy qould then dig her up and she escapes.
So she gets to where the coffin is at and quickly climbs in and hides waiting in the dark for the coffin to be buried.
So the coffin gets buried then she lights a lighter to see who she shared the coffin with...the morgue guy.
The camera dollys up from above her unplanned grave with the muffled screams getting quiter as the camera goes further away.
It was awesome enough a twist to stick in my mind for 20-odd years.
It also created a mindset of suspicion always waiting for a twist that ruined Shyamalan's chances at getting me twice after Sixth Sense.
Whilst Im having difficulty locating the remade 80s version I refer to, I found that the 80s series appears to be a remake of an earlier, 50s Hitchcock series...! Heres the original equivalent episode.
