Affleck and Damon lend their star power to the first few episodes of “Project Greenlight.” Affleck, the rambunctious one, does a wicked impersonation of Jay Leno one minute, then violates protocol when he phones Miramax boss Harvey Weinsteindirectly to lobby for a bigger “Summer” budget, much to Gordon’s chagrin. Damon comes across as a witty straight-shooter,snorting contemptuously when someone suggests a scene set in Lake Michigan could be shot more cheaply in a swimming pool.
