Iron Man director Jon Favreau has confirmed the news on Twitter.
'Please stop asking if Harrison Ford is in Cowboys & Aliens. Okay?' the New York Daily News quoted Favreau, as tweeting.
He added, 'He is. Please don't tell anybody.'
James Bond actor Daniel Craig and sexy House doc Olivia Wilde will also star in the flick.
Favreau will helm the project, with Lost executive producer/writer Damon Lindelof co-writing the script with Mark Fergus
