We haven't heard much on a follow-up to last summer's Indiana Jones and the Kingdom of the Crystal Skull, but it seems like the series' star is ready to reprise his legendary role. MTV recently spoke with Harrison Ford, who was promoting his new film Extraordinary Measures, and spoke a bit about Indiana Jones 5 as well.

"I think it would be interesting to deepen the relationship between he and his son [Mutt, played by Shia LaBeouf] and play on that relationship. ... It's full of opportunity. The series is full of opportunity."
