Iron Man 2 helmer Jon Favreau has confirmed a Latino Review scoop that Harrison Ford is joining Daniel Craig and Olivia Wilde in the director's graphic novel adaptation Cowboys & Aliens.

Favreau posted the following on his Twitter account.

Please stop asking if Harrison Ford is in Cowboys & Aliens. Okay? He is. Please don't tell anybody.

Based on the Platinum Studios Comics graphic novel written by Fred Van Lente and Andrew Foley, the sci-fi Western explores what would happen if the traditional Old West enemies -- cowboys and Native Americans -- found the prairie attacked by aliens in mid-1800s Arizona.

The DreamWorks and Universal movie is targeting a July 29, 2011 release. Alex Kurtzman, Roberto Orci and Damon Lindelof wrote the script.
