Watching the 9x08 Cockroaches commentary (featuring Billy Petersen, William Friedkin and Dustin Abraham) as I was excited to see Billy talk about the show but I cannot stop laughing at Friedkin’s enthusiasm. Billy and Dustin are barely getting a word in edgeways. Every actor is “fantastic”, he is explaining the construction of scenes and how to write for screen but in a Screenwriting 101 way and Dustin is like “you taught us about shoe leather” and then nobody explains shoe leather (it’s the idea of ‘burning shoe leather’, ie don’t have a character say they’ll travel somewhere and then go there, have them just show up. It does make for humorous plot issues when characters have travelled together but suddenly want to discuss things when they’re at the place, suggesting the journey was made in absolute silence – Immortality addresses it really nicely when Grissom and Sara get out of the car and Sara says they were in silence for 30 minutes)
