in the bar scene with Walken when it's showing the other mobsters I would swear they had Johnny Depp walk across the screen, look dead into the camera and keep moving. He never said anything, but I'd swear that was him.
I rewinded it and rewatched it mutiple times and even paused it. It was definitely Depp. And thats definitely a Johnny Depp thing to do...make a 1 second cameo in a super low budget Crackle original movie...even though he could have been doing anything else. Thats why i love him...he doesnt take himself too seriously and has a sense of humour.
Totally agree with your opinion on the man but that wasn't him. Looked A LOT like him though. The character also appears a few minutes later in the montage and you get a little longer glimpse and can see the differences. But that was a Depp-like pose at the beginning there.
