Harrison Ford was a guest on last night's 'Jimmy Kimmel Live!' to promote his movie '42' and naturally the discussion came around to 'Star Wars: Episode 7' and the future of the franchise. Ford tried to stay mum and say he couldn't talk about anything 'Star Wars,' but when he agreed to some questions from the audience, things got heated and Ford walked off the set. Watch video of the incident below.

OK, we can't keep up the ruse: it was all a bit and Harrison Ford really wasn't angry, but this is a funny video regardless. We don't want to give away the punchline but after "answering some questions" from 'Star Wars' geeks in the audience, a familiar face from Ford's past shows up to ask the actor a question and that's when things get testy.

Few people play pissed off as well as Harrison Ford who eventually launches into an expletive-filled tirade, calling the audience member a "sack of s---" and a "son of a b---" before storming off. Of course it's all in good fun and we think you'll get a pretty good laugh out of it.

Of course, Ford really can't talk about 'Star Wars: Episode 7' as Disney and J.J. Abrams plan a big announcement for this summer, likely at Comic-Con or the D23 Expo.
