The Grateful Dead are among a handful of legendary rock groups -- Led Zeppelin and the Beatles also belong in this category -- whose music is almost impossible to license in a film. Unless you have a massive budget to spend on music rights (cough, Cameron Crowe), the likelihood of using 'Hey Jude' or 'Misty Mountain Hop' in your movie are close to zero. However, the Grateful Dead may no longer have this problem. According to Deadline, ICM has been given access to the band's catalog and will produce a feature film built around their music. ICM's Bruce Kaufman, who did something similar with the Beatles for 'Across the Universe,' will be heading up the project.
