This matches what I said, I think, Peter probably regarded Wisdom as being over the top off stage also, to the point of becoming impolite like he did with the queen. Wisdom may have been a nice person, I don´t know, but a character trait like that would possibly put Peter off altogether.
@ Stewpot:
How interesting, I can see what the saying means. I have met a few actors, also some of the LOTSW cast during a lunch event 2 years ago and on another occasion, and some of them were, well, let me put it that way, not my cup of tea. A few were behaving sort of arrogant and pompous at times. Juliette Kaplan wasn´t my favourite, and Liz Fraser neither, she seemed to be really arrogant, she never even looked at others. I liked Jean Ferguson and Burt Kwouk best from those I met.
With Peter I must say he is just as likeable as Cleggy, very nice and gentle person, very respectful to others (also to fans who bump into him somewhere and want a chat or a photo) and a great humour. Definitely a "Go and meet your hero!"
