I won't buy the Argo special edition Blu-ray, since I already bought the DVD and have seen the movie plenty of times on HBO in recent weeks.
But the bonus feature on the "Argo fuck yourself" joke (via Esquire) looks pretty funny. At 51 seconds, it certainly doesn't warrant buying the Blu-ray. Nonetheless, it's a chuckle, and the running gag is one of the more memorable parts of the movie.
Interestingly, Ben Affleck said in an interview with Entertainment Weekly that producers George Clooney and Grant Heslov originally envisioned Argo with a more comic tone.
Either you’re faithful to laughs and you’re making a comedy or you’re faithful to the truth of the film. Not that comedies can’t be serious, but the laugh can’t be supreme in the version of the movie I wanted to make. And George and Grant both aspire to that great sort of Coen brothers quasi-comic serious movie, and I just wasn’t confident that I knew how to do that. I was much more confident knowing how to do the other thing, which was just chasing realism.
I think it's safe to say Affleck had the correct instinct here, though Argo certainly had its lighter moments. I'd love to see the original, more comic take, however. I wonder if that screenplay is out there.
