Factual error: All UK driving test instructors must wear a yellow reflective waistcoat or jacket while instructing someone during their driving test. This was still true in 2002 when the film was shot.
Visible crew/equipment: During the scene where there is boxing music being played, as the players are entering the bowling green, a cameraman can be seen following the pair.
Continuity mistake: In the scene after the half-time break in the International Tournement, Cliff Starkey has been to the sea to retrieve his "English Plasic and Asda bag" Bowls and starts playing with these again to improve his game and his luck. When we then see lots of shots of the UK Bowls smashing the Aussie bowls out of the way, (as we make a storming fightback) they are back to the blue ones again. Then it cuts back to the last few ends and he has the black plastic back.
