I Love You, Man
With so much attention (and money) going to The Hangover in the summer of 2009, this R-rated bromance from earlier that year has been too often ignored. However, the original film showed that second fiddle Paul Rudd could be a game leading man, and his chemistry with Jason Segel was first-rate.
With brawnier turns from both actors expected this year (Rudd in Ant Man, Segal in The End of the Tour), perhaps it is time for the comedy actors to get back to their roots, and give Peter Klaven and Sydney Fife another shot.
