The lead actor in Avatar was so unremarkable that I've mentally replaced him with Chris Pratt. Any time Avatar comes up, I think "Who was even in that? Sigourney Weaver, Giovanni Ribisi, Zoe Saldana and I only remember that because she was better in Star Trek that year...the main dude was a white guy? I'd remember if it was Jake Gyllenhaal or a Hemsworth...Chris Pratt? That sounds right."
