Factual error: When M and his entourage arrive at Bond's estate their cars are surrounded by sheep. They then drive on down a unsurfaced road to Bond's house, past a pride of lions he keeps on the grounds. A series of sweeping overhead shots shows us it is all one huge field, with no fences or the like. Those sheep aren't going to last very long .
Trivia: During the "torture of the mind" sequence, one of the bagpipers stops Peter Sellers and asks him if he is Richard Burton, to which Sellers responds, "No, I'm Peter O'Toole." The piper then says, "Then you're the finest man who ever breathed." The piper in question is Peter O'Toole in a cameo, and the exchange is a two-fold reference to the 1965 film "What's New Pussycat?", which starred both O'Toole and Sellers: first, Richard Burton had a cameo in that film and had a similarly surreal exchange with Peter O'Toole; and second, there is a dialogue between O'Toole and Sellers in that film where Sellers says O'Toole is the "finest man who ever breathed."
