10 Most Out-of-the-Box Casting Decisions in Movies, Ranked

Casting is a tricky, tricky science. It's one thing for a great actor to deliver an outstanding performance, but it's something else entirely for a casting director to find the exact actor who's most perfect for any given role. Sometimes, these perfect castings are pretty obvious. It's hard to imagine how anyone otherthan Robert De Niro could have been cast in Taxi Driver, and hard to imagine anyone other than James Earl Jones lending a voice to Darth Vader.
