Harrison Ford is eager to don his iconic fedora once again for a fifth Indiana Jones film -- just not right this minute.

The audience cheered last night on "Jimmy Kimmel Live" when the host mentioned the recently announced sequel, leading Ford to joke, "Not now."

“I’ll be ready," the 73-year-old actor added." "I'll be ready. I’m excited about it.”

The Disney film will re-team Ford with Steven Spielberg, who directed the previous four installments of the franchise. David Koepp, who wrote "Jurassic Park" and "Indiana Jones and the Kingdom of the Crystal Skull," will pen the script.

“The opportunity to work with Steven again, and the chance to revisit this character which has brought pleasure to so many people — not to mention me,” Ford said. “It’s great fun to play this character, it’s great fun to work with Steven. I’m looking forward to it.“
