TriStar Pictures has picked up a tragi-comic pitch called “Mr. Tambourine Man” for Neal Moritz Original Prods. to produce, sources said Wednesday.

TriStar took the project off the table with a pre-emptive bid of low six figures against mid-six figures if the pic is made. Gwyn Lurie and Gary Marks are scripting. Exec VP of production Amy Baer will oversee the pic.

Sources said Brad Pitt has shown interest in the project and incentives are drawn into the deal if he becomes attached.

Project is based on Oliver Sacks’ story “The Last Hippie,” about a father who is estranged from his son at a young age. Years later, when the father finds him again, he discovers that a brain affliction his destroyed his son’s ability to create new memories. The son is trapped in the 1960s reality and the only way they can communicate is through the music and ideas of that era. TriStar is expecting a hit soundtrack to result from the pic.

Brad Luff, who partners with Moritz, is exec producing. David Koawans is co-producing, as are Lurie and Marks.

Jim Rosen and Amy Ferris of ICM brokered the deal for the pitchers.

Lurie is currently at work on “As Fate Would Have It” for Disney. Luff, Jordan Kerner and Elizabeth Guber-Stevens are producing. Other Lurie projects in development include “Being Frank” for MGM and “Fool’s Paradise” for Interscope.

Sacks’ work as as pyschologist and subsequent book provided the basis for “Awakenings,” the 1990 Robin Williams starrer from Columbia Pictures.
