Interviewing movie stars can be a tough gig. Will they be friendly, out-going, and allow you to ask the pressing questions the world wants answers to? What if you freeze, become a pile of sweat and forget how to read what's on your sheet.

A daunting prospect, but if it all goes pear-shaped you could revert back to the film you've just watched. A pretty easy exit strategy, just harp on about what parts you liked, and get the hell out of there.

That is of course if you've seen it, like, even a little bit. I mean, even just one small scene, or if you've given it quick IMDB. Unfortunately for this reporter, he hadn't done any of those things before quizzing Bill Hader and Kristen Wiig on their latest film, The Skeleton Twins, and it wasn't long before they realised.
