There you have it, right from Stallone himself on twitter. This is huge news for Expendables 3 that I bet most of us didn't see coming. Harrison Ford always seemed like a long shot and now at the same time we learn that Bruce Willis won't be in the movie!
(Edit: This has been confirmed)
"GREEDY AND LAZY ...... A SURE FORMULA FOR CAREER FAILURE"
We don't know what role Harrison Ford might have in EX3 but I think it's certainly possible that he could play the president of the United States, just like he did in Air Force One. Personally I think that would be perfect. I also believe that having Harrison Ford as well as Mel Gibson attached to EX3 will generate a lot of hype and interest in the movie which should be good news to action fans.
