Brad Pitt's Revvin' Good Time in London

Possibly looking to add to his motorcycle collection, Brad Pitt stopped by a Honda Goldwing specialist bike shop in London, England on Wednesday (June 13).

After looking around the store, the "Fight Club" actor posed for a picture with a staff member of HGB Motorcycles while offering up a wee smile through his large sunglasses that he wore with a grey sweater and light colored slacks.

On the business front, Brad's latest film, "World War Z" - which he is producing and starring in - has become a bit of a nightmare causing the release date to be pushed back from December of this year to June of 2013.

The zombie film is said to follow a U.N. employee who is racing against time and fate as he desperately tries to stop the outbreak of a deadly Zombie pandemic.

Apparently, the trouble with the film started when Brad hired Marc Forster as the director - who has little experience with effects - because he was forced to work with a more seasoned team leading to several conflicts, according to sources with ties to the production.

Brad will now work with the team to do as many as five weeks of complex reshoots starting sometime in September for "World War Z" which is now said to be costing more than $170 million.
