This is what Alan Rickman’s famous voice sounds like on helium

Alan Rickman - he of the deep, brooding voice, and famous for playing Severus Snape, Hans Gruber, and even Eamon De Valera - brought helium to his interview on Jimmy Kimmel last night.

Apparently, Rickman was none too happy about Kimmel and Benedict Cumberbatch impersonating him on the show - and decided humiliating himselfand Kimmel with a high-pitched squeal.
