Factual error: Aunt Rose died in 1955 and not when Reggie and Frances were on their honeymoon. (02:44:35)
Continuity mistake: Ronnie chucks a man out in to the alleyway on the opening night of the club. The man holds a knife out at Ronnie - the height of it changes between shots. (00:43:50)
Continuity mistake: The amount of blood on the sword changes when it's taken out of the thug's hand. (00:35:10)
Revealing mistake: When the Krays are boxing for the first time, their mum comes in to break them up. She runs up to the ring where a member of the crowd holds the middle rope lower to help her get in the ring. The problem is, he pulls the rope before he sees her making her way to the ring. It can't be a coincidence as he lets go as soon as she's in the ring. (00:26:30)
Continuity mistake: When Reggies knocks the boxer out he falls by the ropes. Camera changes and he's moved away from the ropes.
