Cedar Rapids is a simple, character based comedy that stars Ed Helms, John C. Reilly, and Anne Heche. It's a well written film that makes very good use of it's main players. Helms is amusing as the dorky insurance salesman Tim Lippe. John C. Reilly is back on his comedic game after the disappointing Cyrus. I would suggest Cedar Rapids as a rental. It's a fair watch if you're in the mood for a good laugh that never pushes the envelope.
