When toasting the birth of Robbie's child and Robbie dislikes the whisky, Harry calls him a Philippine. Whilst the usual saying is "philistine", Harry, ever polite and moderate, is softening the criticism by using a light-hearted sound-alike alternative.
When Harry is discussing Robbie's life of crime with him, he says that Robbie wouldn't want to miss his son growing up. This is discussed before the child is born. Later, when Luke (Robbie's son) is born, it is clear that no one knew that he would be a boy before the event.
When Albert is sitting on Rhino's shoulder looking through the pub window you can see the cameraman's reflection in the window on the right of Albert. The cameraman's reflection becomes even more visible after Rhino puts Albert down.
