Classic Horror discussion

I wanted to start a place where we could discuss classic horror movies.  The question is where to determine the line is between Classic and Modern.  After much thought I settled on 1970 as the dividing line.  I'm sorry classic means a movie has stood the test of time.  I honestly don't see Nightmare on Elm street as a classic yet.  Jaws is close and is standing up very well but I still can't call that a classic. Sometimes it is not the movie that makes a classic but the actors:  Vincent Price, Bela Lugosi, Boris Karloff,  the Peter Cushing-Christopher Lee-Christopher Plummer combo.  again Classic. There is one more thing that makes a classic the studio/production company.  Hammer films were known for horror movies period.  I think that qualifies as classic. So any horror classics in this thread; Classic movies, Classic actors, classic studios etc Lets dig up the memories.
