Conservatives were rightly suspicious when they learned a new documentary on President Ronald Reagan would make its Sundance Film Festival debut this month.

The left-leaning festival, a major event for a left-leaning industry, hardly seemed the place for a celebratory look at the conservative hero. Or even a fair one. “Reagan’s” director, Eugene Jarecki, is an open liberal who contributes to The Huffington Post and previously gave us “Why We Fight,” a treatise on the military industrial complex.

But open minds are a beautiful thing, and it’s not good form to critique a movie until you’ve seen it. But we can note Jarecki’s intentions regarding the project. He spelled them out during a Q&A session connected to his film’s Sundance screening.

“I came into this film with an ax to grind,” reports the LA Times film blog 24 Frames.

In the end, he said his mind wasn’t changed despite the years of research and roughly two dozen researchers who helped him. “I didn’t get seduced by Ronald Reagan’s folksy thing,” he said. “A lot of it was stagecraft.”

We anxiously await Jarecki’s upcoming “Obama” documentary focusing on empty slogans and Greek columns.
