Hollywood mogul George Lucas struggled so much with writing the screenplay for final Star Wars installment Episode Iii - Revenge Of The Sith, he had to force himself to stick to a rigid working day as he sought inspiration. The hugely successful movie-maker, 60, took on the persona of a normal office worker as he sat at his desk for nine hours a day, five days a week - and he still only managed to produce five pages everyday. He says, "I am very diligent about writing. I go to work at 8.30am and leave at 6pm. I sit there with that page in front of me but I still can't write it. I do get it done, I actually write five pages a day. But I force myself - otherwise I would probably write a page a day."
It's too bad he couldn't have just sold the rights of the story to somebody who actually cared.
