I love Alfred Hitchcock he direct 53 movies over the course of decades and he would have little cameos in his films 
Hmm, I'm not familiar with him. What movies did he make?
Psycho is probably his most famous film. A secretary ends up being murdered in a hotel after she steals some money. It has a great twist ending. 
Well I hope you didn't just spoil it for me!! So he's a horror director? Honestly I haven't watched many horror films in my life. I find them funny most of the time.
He directed all sorts of films. The plot twist is at the end so it comes as a surprise.
