Deliberate mistake: Frankie's voice-over reading of the letter to his father does not match the text of the letter. He says, "Ricky Munroe told me. Trust him to put his big feet right in it. I've told him hundreds and hundreds of times." but the letter reads, "Ricky Munroe told me. Trust him to put his size threes right in it. He is rubbish at secrets. I've told him hundreds and hundreds of times." (00:21:15)OneHappyHusky
Continuity mistake: When Frankie and Lizzie meet the Stranger on the docks Sunday at 1:00pm, it is quite overcast when the Stranger asks Frankie, "Right. You choose, where do you want to go?" The shot immediately moves to a hillside overlooking the docks and the skies are almost completely clear and blue. We know a narrow window of time has passed based on information on what transpires before and after this scene. (01:10:50)OneHappyHusky
Trivia: In the scene where Ricky Monroe played by Sean Brown free-styles a hip-hop dance move in the hall outside Frankie's flat, that was entirely improvised by Sean Brown who had been "busting those moves" on set and had been the director's intent to work into the movie since she first witnessed them from the beginning of filming, according to the director's commentary.

Nell: I knew something like this was going to happen. I told you, didn't I? What are we going to do?
Nell: Lizzie, darling, listen, I - you cannot keep running, you got to face this sometime. Tell Frankie the truth. He should know what his daddy was. Then maybe he'd stop wishing for him.
