X17online has the first photos of Brad Pitt on the set of Moneyball today in downtown Los Angeles!

The actor was shooting scenes in a high-rise building and, at one point, took a break and headed to his trailer.

Pitt was clean-shaven and appeared to have highlights in his longer hair for the roll of Billy Beane, the Oakland A's general manager who used computer-generated analysis to draft his players.

The film has been plagued with problems that started with a total script rewrite after Oscar-winner Steven Soderbergh's draft was rumored to be too realistic, which equaled ... boring. Sony Pictures then revived the movie with former West Winger Aaron Sorkin as the new writer. Reports say film is much improved and we've seen Brad at the Sony lot frequently over the past month so we're sure he's been heavily involved in the pre-production.

Jonah Hill, Phillip Seymour Hoffman, Robin Wright, and Kathryn Morris co-star.
