Continuity mistake: When Alex Stillman visits Tommy Vinson in his house for the first time, he has a look at some of Tommy's pictures, while Tommy gets two beers. He asks him about the two framed playing cards (jack diamonds and 8 diamonds) underneath which a golden badge is in the frame. The next shot is a closeup of the frame, and the golden badge is gone. There is just black velvet on the place the badge has been.
Character mistake: When Alex Stillman is facing Karen 'Razor' Jones for the second time in the film he calls her All-In with Pocket Queen's in his hand whilst she has AJ of Spades whilst the cards on the table are:Ten of Spades, Jack of Hearts, 2 of Spades and the King of Diamonds. However the commentator then states that either a spade, Jack or Ace will cripple Alex but that is not the case as an Ace would give him a Straight and she would only have 2 pair Jacks and Aces.
