Josh Brolin seems to have done all the casting for his Warner Bros. summer blockbuster JONAH HEX, securing the signature of John Malkovich a few weeks ago. 

Can’t blame him for going for Megan Fox, last year named the hottest woman in the world by FHM. Wouldn’t you pick someone like her to share your love scenes with?

The Hollywood Reporter say Fox will play Leila, a gun-wielding beauty and love interest of Brolin’s HEX.

Malkovich plays a voodoo practitioner who wants to raise an army of undead to liberate the south. Brolin’s HEX is the scarred bounty hunter trying to stop him. 

HORTON HEARS A WHO director Jimmy Hayward helms his first live action movie which begins production in April and is due out August 2010. 

That’s not it for Fox. Today she has also landed the lead in FATHOM. She will play Aspen who learns she is a member of a race of aquatic humanoids who possess the ability to control water.

It’s based on the comic created by the late artist Michael Turner and is setup at Fox Atomic. Looking at the cover art above, it’s like they always had Fox in mind for this character. 

The TRANSFORMERS star is said to have been a fan of the comic since it first hit the stands in 1998 and pursued the project for herself. She will have big creative control over the film, being written by Jordan Mechner, the creator of the PRINCE OF PERSIA video game. 

Back in the late 90’s, James Cameron was flirting with the project, what with his underwater obsession and all but TITANIC drained him so much, he had no interest in making a big movie then. 

I doubt they will struggle to find a director for this one. Surely there will be a cue of people interested in spending a few months with a wet Megan Fox?
