20 Most Expensive Films Ever Made

20. Avatar (2009)

Rating: $425,000,000

Worldwide Box Office: $2,783,918,982

Was It Worth It: Had it cost a billion it would have been worth it thanks to that return. And while it's a little concerning to wonder about the future of the franchise with two entirely unnecessary sequels incoming, the original remains an incredible feat.

Not bad for a Fern Gully rip-off.
