Comedian Will Arnett (Arrested Development) and recent Oscar Nominee Michael Shannon (Revolutionary Road) have just officially joined Warner Brother’s upcoming 2010 summer tent-pole Jonah Hex. Arnett will be playing a union soldier who enlists Jonah Hex and is blindsided by the dirty fighting style of his enemies. Michael Shannon is set to play Doc Cross Williams, the bizarre ringleader of a brutal gladiator circus event. That character also may be featured in future installments. The cast already includes Josh Brolin (Milk), Megan Fox (Transformers), and John Malkovich (Being John Malkovich). Jonah Hex is set for August 6th, 2010.

Will Arnett seems like an odd casting choice, but then again it’s Will Arnett so it would be a sin to call this bad news. Michael Shannon is of course great news. While it sounds like more of a cameo, Shanon will still most likely be great as he usually is. 

What do you think of this cast? Are you excited for Jonah Hex?
