Lee Daniels has credited late Hollywood producer Laura Ziskin with bringing The Butler to the big screen as she refused to give up work on the film even as she lay dying. The moviemaker brought the celebrated producer onboard to help him secure financing for his historical epic, and reveals she gave up a lucrative job on the last Spider-Man film because she was so passionate about his project. Daniels also admits Ziskin continued fighting for The Butler's financing right up until her death from cancer in June, 2011. He tells Comingsoon.net, "Laura Ziskin... God rest her soul, quit the last Spider-Man to do this film. When the studio didn't do it, she went out and began raising money and we continued developing the script, even on her death bed. Literally I was with her developing the script a week before she passed away and (she was) raising money for the film a week before she passed away, from her bed. "(She was) an incredible woman." Lee Daniels' The Butler hits cinemas this month (Aug13).
