We weren't exactly lacking in confidence in Favreau to begin with, but he's certainly got a solid team together behind the camera. Heavyweights Steven Spielberg, Ron Howard and Brian Grazer are all on hand as producers, should Favs need any advice from a bunch of movie geniuses.

The script comes from the current Hollywood go-to guys, Alex Kurtzman and Roberto Orci. While the pair have knocked up some dubious scripts in the past (both Transformers outings, for example), they've proven that they can deliver the blockbuster goods with Star Trek and Mission: Impossible III.

Speaking to Collider about the script, Orci said: "We've sent ourselves back to school and we're watching Westerns together and analysing them. We're really getting into it... We just watched The Searchers."

Kurtzman chipped in: "We had a lot of these Westerns in our head, but Jon is an incredible fountain of Western knowledge... Because he's an actor, he knows what plays and doesn't play very quickly. We're having an unbelievably good time working with him."

Here's hoping Favreau gets the best out of them.
