Revealing mistake: When Alfie (Michael Caine) goes to the dry-cleaners, he starts kissing a woman. He has a grey suit on and he comes out wearing a blue suit, being a comedic trick. But, when the guy in the grey suit goes behind the clothes rail, you can tell it is not Michael Caine, as his hair is shorter and blonder than Caine's.
