Clearly having fun on the day we caught up with them, Rafe Spall and Sally Hawkins were on fine form when telling us about their latest film, X+Y. The movie hits UK cinemas Friday 13th March and you can read our review here.

We’ve already seen an interview with Rafe and Asa but now it’s time to get sexy as we chat ‘Sexy Maths’! – you’ll have to watch the video to find out what that’s all about – we also spoke to the two stars about:

– Working together again

– Improvising on set

– Taking tips from the original documentary the film is based on

– How they coped with Maths when they were younger

– Working with young star Asa Butterfield
