Surprising Unknown Facts About Hollywood Movies

7.Blockbuster Titanic

The lead male role was played by Leonardo DiCaprio as we know, but the first name on the table to play Titanic's very romantic lead was in fact Matthew McConaughey. Can you picture him in it?

8.The Hitchcock Thriller "The Birds"

Another great horror story, The Birds aired first in 1963 starring Tippi Hedren who is in fact Melanie Griffith's mother! The movie was filmed long before there were special effects, so one scene in the attic where poor Tippi is being pecked for hours took a whole week to film. She was definitely exhausted!

9.Jim Carey

It is rather surprising to discover that Jim Carey turned down this particular role pretty early on. The thing is can you even imagine him in it now thanks to Johnny Depp?
