Finally, Quentin Tarantino‘s back to doing what he does best: resurrecting the careers of burned-out stars. And this time he’s got his work cut out for him. Tarantino has cast blaxploitation star Pam Grier to play the title role in his long-awaited Pulp Fiction follow-up, Jackie Brown. Although Brown is based on the 1992 Elmore Leonard novel Rum Punch, Tarantino has rewritten the role — a stewardess-cum-hooker caught up in a plan to double-cross a gunrunner and the FBI — specifically for the actress, who recently turned up in Mars Attacks! and Escape From L.A. More interesting still is who may be joining Grier in a search for career daylight. According to sources, Sylvester Stallone, fresh from his indie stint in Miramax’s Copland, is in negotiation to play a superslick gunrunner in the $10 million movie. Stallone’s spokesman insists that the actor’s ”next project is not set yet.” Bridget Fonda and Pulp Fiction player Samuel L. Jackson are also expected to star in the film, which could be ready for release in late ’97.
