Here's a gesture that threw me; a guy brushing dust off his suit. Sounds simple, but I had to do a lot of sketching before I came up with anything that even came close to suggesting the movement I was looking for. As a last resort, I was going to try for a "strobe" effect but I didn't want to overdo it and call more attention to the action than I needed to.
I'm very happy to see that Turner Classic Movies is showing Jules Dassin's masterpiece Rififi (or Du Rififi Chez les Hommes) tomorrow night. It's a classic Film Noir with one of the coolest heist scenes you'll ever see. I love sooooo many things about this movie, not the least of which is the sad, world weary face of the star, Jean Servais. This sketch doesn't do him justice so I may have to try again some other time.
