He has one of the most distinctive voices in modern cinematic history, but just what does Alan Rickman sound like on helium?

The star of Die Hard, the Harry Potter series and the Barchester Chronicles (Peep Show fans, hello) was on Jimmy Fallon earlier in the week and, sure enough, the helium balloons went up.

Because, y'know, that makes perfect sense.

Anyway, Rickman - who is a good sport about his voice, seeing as we asked him about it once - was more than happy to take the mick out of himself.

Admit it, you've always been curious about it. And now you know.

But why didn't they get him to do some lines? WHERE ARE MY DETONATORS?!
