how do I get my hands on this film?

I think just about the only way for you to get hold of it is online. Amazon are fairly easy to use and buying stuff online tends to be a step by step process which is explained as you go so nothing to be worried about. I think Mesmer is only available on region 2 (Europe) and possibly region 0 (region free). Here are some links you can try as Amazon can be expensive.
