We reported yesterday that Colin Farrell had signed on to a new comedy and it seems that cast could be growing by three more. According to The Hollywood Reporter, Jennifer Aniston, Jason Bateman and It's Always Sunny in Philadelphia star Charlie Day are in talks to join the cast of Horrible Bosses.

The film will focus on three longtime friends who all become so fed up with their jobs they decide to kill their bosses. Bateman and Day would play two of the three friends, with Bateman's character believing that hard work will pay off in the long run, until he is denied a promotion he thought he deserved, which causes him to hit rock bottom. Day will play a guy with seemingly perpetual bad luck and it was said that the third friend, who has not been cast, will be a ladies-man-type who actually excels at his job, until his boss dies and is replaced by a less-friendly boss.

It was said that Colin Farrell would play one of the bosses. Jennifer Aniston would play an aggressive dentist who hits on Day. New Line is reaching out to top talent for the other two boss roles. Seth Gordon is directing the film based off a script by John Francis Daley and Jonathan M. Goldstein. Michael Markowitz wrote the original spec script.
