There is a very good chance you've never heard of C.O.G. Premiering in Sundance's U.S. dramatic competition, it was mostly overlooked both at the festival and then later during its theatrical run. I loved it, especially Denis O'Hare's supporting turn. At Deadspin, Will Leitch and I each pick our favorite forgotten movie performance of 2013. Seemed like a good opportunity to sing O'Hare's praises, which I do here.
