Le Passe-muraille on AllMovie

Mr. Peek-a-Boo may seem like a puerile title, but it is a lot more graspable to non-French audiences than the original Garou Garou Le Passe Muraille. Bourvil stars as a minor bureaucrat who finds himself the reluctant recipient of magical powers. He is actually able to walk through solid walls, which should be no surprise to those who read the novel on which the film is based, Marcel Ayme's The Man Who Walked Through Walls (truth in advertising!) He resists his friends' suggestions that he utilize his power to commit undetectable thefts, but changes his mind when he meets reluctant thief Joan Greenwood. The special effects by Henry Harris and Paul Raibaud are fairly elementary, but good for a few laughs as Bourvil constantly makes monkeys of the gendarmes.
