Not counting the Slim James Bond used in "Goldfinger", what razors have you spotted in movies? I'm watching Pink Floyd "The Wall", and just got to the scene where Pink's shaving his body with a ball-end Tech... (Yeah, TV shows, too)
Watched "The Apartment" with Jack Lemmon and Shirley McClain. In one quick scene he starts to shave, realizes he's hidden the blades, opens what appears to be a Super Speed and puts the blade in...
The George Romero flick "Bruiser" made in 2000' has the best shave scene ever at the very beginning of the movie. Couldn't find a YouTube clip but he uses a Gillette g1000 with a wilkinson sword uk blade and Palmolive shave cream. It's the movie that got me into wet shaving.
I can't find a clip for this one either, but there's a scene in Steve Martin's DEAD MEN DON'T WEAR PLAID where he shaves his tongue!
