Not even age can get an actor down: Harrison Ford is ready for another Indiana Jones movie.

The screen legend, who has played the titular adventuring archaeologist in the four previous films in the franchise, said he is keen to make a fifth film, and creator George Lucas is already working on ideas.

Harrison, who also starred in the original Star Wars trilogy, said, “I’d love to do it. George Lucas is working on an idea and if he can come up with something, Steven Spielberg and I have to agree to go ahead with it. If we find another story to do and we develop the character a little further and I get a chance to do another one, I’d be happy as pie to do it. I don’t think there’s any other franchise films that I’d want to go back to.”

The 67-year-old star particularly wants to deepen the relationship between archaeologist Indy and his son Mutt Williams, played by Shia LaBeouf in 2008’s Indiana Jones and the Kingdom of the Crystal Skull.

“I’d love to see a development of the relationship between him and his son and him and his new wife. I think it’d be fun. The series is full of opportunity.”

He has also spoken about how he would like to work with actress Karen Allen, whose character Marion walked down the aisle with Indy in the last movie: “Karen’s a wonderful actress, I’ve always enjoyed working with her. I’m hoping that there’ll be a part for all of us in the next one.”

However, the actor insists he won’t play the role forever. “I don’t think I’ll do it in a wheelchair.”
