Science Goes to Hollywood: Science Fact V Science Fiction Brian Cox and Robin Ince continue their tour of the USA, as they take to the stage in LA. They are joined by cosmologist and science advisor on movies such as Thor and Tron Legacy, Sean Carroll, comedian Joe Rogan, The Simpsons' writer and Executive Producer of Futurama, David X Cohen, and Eric Idle. They ask why so many movies now seem to employ a science advisor, whether scientific accuracy is really important when you are watching a film about a mythical norse god and whether science fact can actually be far more interesting than science fiction.
