Patton Oswalt’s career as a writer and actor has been on an ascending curve over the last couple of years, most notably since he provided the voice (and inspired much of the character) of Remy, the rat who dreams of becoming a gourmet chef, in Brad Bird’s terrific 2007 PIXAR film, Ratatouille. He plays his first on-camera leading role in Big Fan, written and directed by Robert D. Siegel — the former editor of The Onion, and the writer of last year’s critically adored The Wrestler — which premiered at the Sundance Film Festival last month.
