Well, I have to say I enjoyed the movie version of “The Mouse That Roared.” There were definitely some differences from the book — I am certain that in the book, Tully did not realize he was supposed to lose. In the movie, he seems aware of the fact (but not so convinced that he turns down an opportunity to win).
I was delighted to see the great British character actor Leo McKern (“Rumpole of the Bailey,” “The Prisoner”) in the movie, as well as William Hartnell.
Who is William Hartnell, you say?
He certainly is.
William Hartnell was the original 1963 incarnation of “Doctor Who.” I have only seen very brief snippets of him in that role; he was surely removed from the second-banana character he plays in “The Mouse That Roared.”
Anyway, I enjoyed the movie, and would recommend you catch it the next time TCM shows it.
