Mitt Romney mocked the director of a documentary released by President Barack Obama's re-election campaign this week.

Calling the film, which has a trailer narrated by Tom Hanks, a "17-minute infomercial," Romney hit back at director Davis Guggenheim's claims that he couldn't find fault with the president. Guggenheim told Piers Morgan on Thursday that, "The negative for me was there were too many accomplishments. I have 17 minutes to put them all in there."

"I'm in awe of him," Guggenheim said of Obama.

"Well, I have some suggestions for the president and the producer," Romney said at a rally. "First of all, talk to the 24 million Americans that are out of work or underemployed in this country. ... I'll tell you, I've got a long list of people for that producer to talk to, and I'll tell you, if someone's looking for things that the president's done wrong, it's a long, long, long list."
