A comic genius like Peter Sellers comes along only very rarely. As an actor he was remarkably versatiles. In particular in the cold war satire "Dr Strangelove" he played several characters leading upto a memorable climax.
Of all his films my favourite are probably the Pink Panther Series in which Peter played the hapless Inspector Cleauseau.
Even if you have seen the Pink Panther films many times you will enjoy this compilation video: The Best of Pink Panther
The ability to do impersonations is often the sign of a great comic. Here Peter Sellers gives us a seemless impersonation of the various English accents, from Cockney to Queen's English. - I'm English and I would struggle to do any of them.
