Beleaguered young actress Lindsay Lohan was sad on the set of Bobby, the star-studded movie about the events and people involved in the 1968 assassination of Robert F Kennedy written and directed by Emilio Estevez. She had to choose between visiting a close friend, possibly for the last time, who was dying in the hospital or continuing her work in the film. But since Estevez had only a short amount of time to shoot major scenes, including one in which Lohan’s character gets shot, literally, ” I had to stay and shoot it,” she said. “My friend ended up passing away that same day, so the scene is really personal for me. It was the most tragic one I’ve ever had to do and required the most acting.”
