He's been shot at, driven across Russia and the Ukraine to report on the making of one of the first post-Soviet horror films and runs out of breath weekly while lambasting the "con" of 3D cinema on his 5 Live show.
Now Mark Kermode – film critic, Observer writer and author of It's Only a Movie and his new book, The Good, the Bad and the Multiplex – will be answering your questions during a live webchat on Friday lunchtime.
In the words of the man himself, The Good, the Bad and the Multiplex, "takes us into the belly of the beast to ask: 'What's wrong with the modern movie business – and how can we make it right?'". Here's your chance to chip in with your questions: What's Mark's masterplan? If 3D won't save us, what will? And why won't he leave that nice Matthew McConaughey alone?
An excerpt from The Good, the Bad and the Multiplex – in which Mark explains why blockbusters are rubbish and why we keep watching them regardless – will run in Sunday's Observer.
Mark will be online at guardian.co.uk/film between 1-2pm on Friday 26 August. Post your questions below to get him started. We warn you: once he's off, there may be no stopping him ...
