Gavin Free suggested playing to 500 points. Geoff Ramsey says in the movie that he regretted it when Gavin said it.
In the later parts of the movie, a purple square is visible on Free's screen.
During the credits, at 2:37:58, you can see that the editor has misspelled the word, "Producer" as, "Porducer."
There was a very unsubtle actor change at 1:21:55 where the character BM Vagabond goes from being played by Ryan Haywood to Jack Pattillo.
