2.Leonardo DiCaprio regrets that he had to turn down the role of Dirk Diggler in Boogie Nights in order to star in Titanic.

4.In Forrest Gump, Kurt Russell provided the voice of Elvis Presley.
5.Someone at Pixar accidentally deleted all the work that had been done on Toy Story 2 — while the film was in production — from the studio's internal computer server.

16.Julia Roberts was the one who convinced Richard Gere to costar with her in Pretty Woman (which he had initially turned down).

17.Bruce Willis was a huge fan of Reservoir Dogs and wanted to work with Quentin Tarantino — and reportedly wanted the lead role of Vincent Vega in Pulp Fiction (which he had heard about from Harvey Keitel). Unfortunately, by the time he met Quentin, the role had already gone to John Travolta.
18.In an early version of The Lion King, Scar ends up raising Simba (after he kills Mufasa).
