Meet Douglas H. Shulman, the 47th Commissioner of the Internal Revenue. He presides over the Internal Revenue Service and probably doesn't have time for too many movies.
If he did relax with a movie before April 17 (this year), he might like one of the following comedies or dramas depicting everything from rogue I.R.S. agents to creative tax preparers. And if you can't find a connection, watch them again employing six degrees of separation between the film characters and the I.R.S.!
