This week's theme is open but there seems to be a 'dance' undercurrent. I will therefore go with my top three dance sequences in movies that a guy has actually watched (or will admit to seeing):
3. Pulp Fiction - John and Uma - you've got the moves!
2. From 9 and 1/2 Weeks - Kim's got some moves!
1. A Clockwork Orange - Singing in the Rain (it starts at about 2:10 into the clip)
A warning this is a violent scene...
