John Cusack is going to play Rush Limbaugh in a biopic -- will it be CGI?

A new biopic about [insert politically biased job description here] Rush Limbaugh was recently announced, and while the rumored directing choice makes perfect sense -- Betty Thomas, who directed the Howard Stern semi-biopic Private Parts -- the person in talks to play Mr. Limbaugh is the comparatively young and svelt John Cusack, who is also interested in producing. Okay, so I've been offline for a while, what with Sandy knocking out my power for a week and stuff. But considering the weight Cusack will have to gain to play this role, similar to how Robert DeNiro packed it on to play Jake LaMotta, has anyone made any jokes about this movie being called Raging Bullshit yet? Surely, I can't be the first. (via Movieline)
