Here's a nice clip from Rudy. A lot of great eye reference from Charles S Dutton (another great underrated actor). Very interesting double & half blinks. I saved out a gif to really show what was going on there. There's no one universal way to blink, and changing up the timing/speed can convey all sorts of different emotions.
I'm excited to announce a new class I'm teaching this coming April on Body Mechanics. It's an 8 week course and should be a blast!!
