I have not seen it anywhere yet but I think I sorted out who plays who in the school bus scene of the movie. It was thanks to this interview with Yvonne Robrts (as First Prostitute):http://welcometotwinpeaks.com/actors/fi ... he-scenes/
the credited actors are:
Chris Isaak as Special Agent Chet Desmond (obviously)
Jon Huck as FBI Agent (also the sound mixer)
Mike Malone as FBI Agent (also the set dresser)
Joe Berman as Bus Driver (also an actual crew driver)
Yvonne Roberts as First Prostitute
Audra L. Cooper as Second Prostitute
plus we can see
uncredited actor as a 4th FBI Agent
The agent with glasses on the right side of the screen is called Gene in an unscripted line of Chet.
With the interview, we know that Yvonne plays the prostitute with a skirt and that an FBI Agent is portrayed by a man firstnamed Brian, sporting a mustache. Mike Malone is already known to be the FBI Agent with a cast on his left hand and has his face on IMDB so that's easy.
So,to sum it up, on the large picture used on your site that would be:
____________________________________________________________________________________FBI Agent (cast on left arm)
_________________________________________________________Bus Driver____uncredited FBI Agent (mustache)
____________________________________________________________________________________________________FBI Agent Gene (glasses)
Audra L Cooper_____Yvonne Roberts_________Chris Isaak
Second Prostitute____First Prostitute (skirt)___Agent Chet Desmond (well, duh)
Furthermore the credited extras are in this order, going right to left. So I have very little doubts about my conclusion.
I suspect Brian to be one of the crew members, like the other FBI Agent extras, and the only Brian to be credited is Brian Bernstein as an assistant camera. Do any of you know if this could be the same Brian or not?
(completely unrelated but I noticed that in the Missing Pieces, the Pink Room is actually named 'the power and the glory' in the 2 places the script uses 'partyland', ie the name on the door and in discussion between Laura and the unnamed truck driver whose performer will come back in the revival. This does not seem to be common knowledge among fans)
