The 67-year-old star had been rumoured to take part in the sci-fi western earlier this week, and the film`s director Jon Favreau has confirmed on twitter Harrison will be in the movie. He wrote: "Please stop asking if Harrison Ford is in Cowboys and Aliens. Okay? He is. Please don`t tell anybody.(sic)" Harrison will join current James Bond Daniel Craig in the movie, which tells the tale of a band of Native Americans and Western settlers who fight for survival following the crash landing of an alien spaceship in Arizona. Harrison`s acting career has been quiet recently, although he has two films out this year. As well as Tom Vaughan`s `Extraordinary Measures` alongside Brendan Fraser, he will also hit cinema screens in November as Mike Pomeroy in comedy `Morning Glory` with Rachel McAdams, Jeff Goldblum and Diane Keaton. Currently in development is Harrison`s fifth `Indiana Jones` movie - the follow up to 2008`s `Indiana Jones and the Kingdom of the Crystal Skull`. `Cowboys and Aliens` - which is based on a 2006 graphic novel of the same name - is scheduled for release on June 24, 2011.
