John Goodman will portray a real life make-up artist that rescued six hostages from Iran. I don't think he'll be able to draw on his experience playing Babe Ruth for this one.

No one said that rescuing hostages was going to be easy, but no one said that it had to be this complex either. Ben Affleck's Argo is based on the 1979 hostage rescue mission in Iran. The government claimed the diplomat taken hostage were actually a film crew scouting locations for a film called Argo. And that's the story of the ACTUAL film  called Argo. It's possible that Affleck's film could also be a ruse, but contemplating that makes my head hurt, so we'll ignore that possibility.

In order to get their hostages back, they needed some legitimacy, so they hired real-life make-up artist John Chambers (Goodman) to sell the whole affair to the Iranian powers that be.

Goodman joins Alan Arkin in the film, which requires the cast to live together in squalor for two weeks to get their heads right for their roles. Take that, rich, famous actors! (Variety)
