Movies from an Alternate Universe

"Awhile back a friend of mine forwarded me a site where an artist had made posters of films that, title wise, we were familiar with, but there was a slight difference; they were remade as if they belonged to a different era or a different genre, the name of the movie was there, but the actors were different, the style was different, and I loved the concept. So I went forward with this theme; what if movies we were all familiar with were made a different slice of time? Who would be in it? Who would direct it?"
These are fantastic. Via Collider.
