Annap you are so right about Sellers in Strangelove. The Presidents call to the Russian Premier is THE funniest moment in cinema. I always wondered how much of that was scripted and how much was ad-libbed by Sellers.

Well Sergey, we have this General and he went a litte...funny. Just funny thats all. And you know what he went and did? Well I'll tell you what he did. He sent a squadron of planes...to bomb your country. (pause) Well how do you think I feel about it!
