If a movie in the works about comedian George Carlin is anything like a previous biopic about another edgy comic who championed free speech, it should be well worth the effort.

Screenwriter Stan Chervin, who earned an Oscar nomination for Moneyball, is penning the screenplay for the still-unnamed film, The Hollywood Reporter said Monday.

Carlin, who died in 2008 at age 71, made about 130 Tonight Show appearances and more than 20 solo albums, the trade publication noted.

But he may be best known for his Seven Words You Can Never Say on Television routine, which, Variety reported , is largely credited with forcing a Supreme Court decision on how much power the federal government should wield in enforcing speech standards on the radio.
