'A Beautiful Mind' Robert speaks to film director Ron Howard about his new movie A Beautiful Mind. The film stars Russell Crowe as troubled math genius John Nash. Nash suffered from acute mental problems, but went on to pull himself together and also win a Nobel Prize. Howard says there is no special camera angle or lighting that can show great intelligence and that the actor's eyes must signal interior brilliance. With Crowe he found that. Howard also says Nash's story offers hope, while showing the honest pain of mental illness.
