Grass Roots is a proposed British-American adult clay film based on the Fabulous Furry Freak Brothers underground comic strip created by Gilbert Shelton.

The government develops genetically modified marijuana as part of the War on Drugs, and Norbert the Nark accidentally gives the prototype to the Fabulous Furry Freak Brothers.

With the government on their trail, Phineas T. Phreakears, Freewheelin' Franklin Freek, and Fat Freddy Freekowtski are forced to leave town, acquiring a remote plot of land in order to fulfill their dream of retiring to grow marijuana in the country.

Grass Roots was going to be directed by Dave Borthwick, whose previous credits include The Secret Adventures of Tom Thumb and The Magic Roundabout.

[5][6] As of 2012, the film was still in pre-production limbo, with the producers still unable to raise the necessary budget; they are reportedly adapting the story into a stage musical.
