If I could think of two actors I would want to be President of the United States in real life, not just fictional, it would be Aaron Eckhart and Morgan Freeman. In this "White House is under attack movie", you will get both. After being released from duty in the Secret Service, Gerard Butler plays the guy that will (likely) save the day. It looks like big budget fun, but also being from Antoine Fuqua, there might be some good drama in there.
In the land of originality in Hollywood, there are two "White House Under Attack" films being released this year. The other is Roland Emmerich's White House Down, and I'll wait for a trailer to make a judgement, but just don't know if I buy Jamie Foxx as the President of the US. Oh, and I still have trouble seeing Channing Tatum and not thinking he is about to pull his tear-away pants off as in Magic Mike.
