Harrison Ford has already been confirmed as returning to the role of Han Solo for the Star Wars: Episode VII movie and he has also been linked to possible returns to past roles, such as Indiana Jones and Deckard in the Blade Runner sequel. Now, Harrison has opened up about the possibility of returning to these roles, admitting that he would not rule anything out.

Harrison Ford as Indiana Jones
Ford was in an interview with MTV, when he explained, "It might be nice, depending on the circumstances, to revisit any one of those characters. What interests me now is the opportunity to work at all and to work in ambitious projects."
He added, "I can't think that way. What I'm looking for is the next opportunity, the next ambitious opportunity. It doesn't matter if it's one of those. If it's one of those, great. If it's not, that's fine too."

Abrams and is set to be released in 2015.
