"Stiff Upper Lips" pokes fun at the crustiness of the British upper crust as it follows a silly ensemble of aristocrats from England to Italy to India and back. Those who groan at puns and mutter "humph!" at wry humor will likely enjoy "SUL" while those who don't will suffer the opposite reaction. How enjoyable this film is will depend solely on the sense of humor of the viewer. Funny or not, "SUL" is undeniably a jolly well done spoof.
