Brad Pitt has reportedly pulled out of the lead role in the comic film "The Watchman" so that he can journey through the US on his motorbike.

"Brad was interested in playing the Watchman, a spoof character in the comedy, but has decided to embark on a tour of America instead," Femalefirst quoted a source as saying.

"He is hoping to ride around with his brother and discover parts of the states he's never seen before."

"The Watchman" was set to start shooting later this year.

The "Troy" star has also splashed on a new beachside bachelor pad after announcing the split from his wife Jennifer Aniston in January.
