On Twitter moments ago, CNN's Piers Morgan announced that actor Gerard Butler would join him as a guest for the White House Correspondents Dinner.

Butler is the star of the 2011 action film 'Machine Gun Preacher,' which features a drug dealing biker character that finds God and goes to Africa to do missionary work. After African war lords attack his camp, the character turns to automatic rifles such as an AK-47 to defeat them.

"This is serious, intense. It's visceral, it's raw, it's everything you would want in a powerful movie," Morgan said, during a 2011 interview with Butler about the film. "It's a remarkably powerful and important film. I hope everyone goes to see it, because it really does telling an extraordinary story."

The film is rated 'R' and has a 29% rating on Rotten Tomatoes.
