James Cameron's budget-bursting blockbuster — which reportedly cost in the neighborhood of $300 million — used state-of-the-art motion-capture and 3-D technology to bring the Na'vi (and their home turf, Pandora) to life. Did it pay off with audiences? Well, if you consider earning $2 billion and becoming the highest-grossing film of all time ''paying off,'' then yes, yes it did.

Willy Wonka & the Chocolate Factory (1971)
