The cast of Warner Bros. Jonah Hex is currently re-shooting 12-pages worth of scenes to punch up the action for what is expected to now be a tent-pole summer release. The studio has brought in I Am Legend director Francis Lawrence to aid Hex director Jimmy Hayward with the re-shoots.

Hex has been plagued with production problems since it was announced, including the departure of original directors Mark Neveldine and Brian Taylor (Crank). Actor Josh Brolin, who plays Jonah in the film, also told MTV in a 2008 interview that the film’s script was crap and that he had to wrestle with the idea of taking the role simply to collect on the truck-loads of cash he would earn.

He said:

When I first read it I thought, oh my God it’s awful! And then I had a moment a week later and I thought why is it awful? Maybe the thing to do is to do the most awful movie I can find.

I went back to my gut. Is it a sell out? What is it I like about this movie? … It’s so tongue in cheek. It’s so ridiculous. But once I started putting people in my mind and saying what if I put Malkovich in this role then what does this movie become? Now let’s put this producer and director on it and think about how it plays out. Then it becomes fun. Now I love that movie. If you have a great filmmaker come in then suddenly these gags and characters become interesting.

Personally, I don’t care if the chimp from Dunston Checks In plays Jonah …  just as long as Megan Fox is still on board as the hooker.

Jonah Hex arrives in theaters on June 18, 2010.
