Steve Spielberg drops out of ‘Chicago 7’ to concentrate on Tintin Trilogy. Steve Spielberg will no longer direct The Trial Of The Chicago 7. Writer Aaron Sorkin (Charlie Wilson’s War) penned the screenplay, based on the trials of eight Vietnam protesters accused of inciting riotat the 1968 Democratic convention. Sacha Baron Cohen had been persuaded by Spielberg to play political campaigner Abbie Hoffman in the film. Producer Walter F. Parkes explained that the director had quit the project due to the WGA strike and his commitment to the upcoming Tintin film. “He is not going to do it,” Parkes noted. “He kind of had a moment of availability to do it, and the strike got in the way. We were unable to do the script work that Steven felt he needed and then, by the time the strike was over, he had already committed himself to begin production on Tintin. Shooting on the first Tintin movie is due to begin this September.
