George Clooney and Grant Heslov, along with Sony Pictures, have acquired the rights to David Bianculli's book Dangerously Funny: The Uncensored Story Of The Smothers Brothers Comedy Hour for a biopic about the infamous comedy duo.

Brian Hecker and Craig Sherman have been hired to write the Untitled Smothers Brothers Biopic screenplay, which will follow brothers Tom Smothers and Dicky Smothers as comedians of the 60s who went from family-friendly merrymakers to counterculture rabble-rousers. They were the first to introduce hippie ideals into the mainstream, and their act eventually got them on Richard Nixon's enemy list, which saw their popular CBS variety show being canceled.

George Clooney and Grant Heslov will produce through their own Smokehouse banner, but its too early to know if George Clooney will director or star in the project.

Not only will Tom Smothers and Dicky Smothers need to be cast, but actors will also be needed to portray a young Steve Martin and a young Rob Reiner, both writers for The Smothers Brothers Comedy Hour .

There is no production start date at this time.
