Matt Damon goes with his gut on the set of his new movie, The Informant, at Makaha Valley Country Club in Hawaii on Tuesday. Nice pornstache and hair piece!!

Damon, 37, plays whistleblower Mark Whitacre in the true story about a price-fixing scheme involving an agribusiness giant.

The Informant is scheduled for release in March 2009. Steven Soderbergh, of Ocean’s film franchise fame, is directing.

What’s Matt eating/chewing on? An ice chip?
