My feeling about “Full Frontal” is that I would rather have been told about it than seen it, so let’s see what I can do for you:

A film within a film within a film, it’s about whether you can believe what you see. The come-on of a title is not an accurate representation of the content of the film, which could be described as playfully cerebral, although we do see more of David Duchovny than ever before (let’s say his truth is really out there). There’s nothing resembling a plot. And even the actors you like Julia Roberts, Brad Pitt, Catherine Keener, Duchovny are probably not playing roles you’d like to see them play.

From the beginning, we know most of the characters will show up at a birthday party for someone named Gus, but there are only hints of who they are (most of them are in show biz) and how they know Gus. Writer Coleman Hough and director Steven Soderbergh seem interested in styles of communication Is each character direct? Passive-aggressive? A wuss? and in the ways people connect with each other or don’t.

“Full Frontal” is shot on a variety of film stocks, from grainy, dim video to high-resolution film, with the scenes that are the most “real” being the ones that look the ugliest. Anyway, that’s how it seems at first, but Soderbergh has tricks up his sleeve and he means to fool around with our perceptions. Just because something resembles a documentary doesn’t mean it’s true, he seems to be saying, and, conversely, even slick-looking moments between fake-o actors can achieve honesty.

If that sounds interesting to you, “Full Frontal” should provide something to chew on. If not, you probably weren’t planning to go anyway.
