This time we answer a question from a listener about just how wrong we all are. This leads us into a fun discussion about certain films that we personally love, but need to mount a bit of a defence for to other people. Before that we have our Film Buff or Film Buff quiz, which tests our knowledge on roles that had to be replaced mid-shoot due to an actor’s untimely death, the movie 'Almost Famous', 50s sci fi TV shows around the world, 'Star Trek', and the works of Alan Smithee. Do send in more of your listener questions for us to tackle! @nerdfestuk on Twitter and Facebook.
