Continuity mistake: Early in the film before he learns of Ned's death, Jackie says that there are 52 people living in the village, but once he learns of Ned's death, he still says that the winnings will be split into shares of 52.
Continuity mistake: In the pub, when the shot is from the left, the pints of Guinness are not full, from the right, they are full. (00:10:00)
Continuity mistake: At the end of the movie in the pub when the lotto man awards "Ned" his cheque, Jackie pins it on the dart board with a dart in the front center of the cheque. In the very next shot, the dart is placed somewhere else.
Continuity mistake: The David Kelly character had an MZ motorcycle. At different times of the film his foot is seen in close up kickstarting it. The kick starter apparently changes sides from the left to the right side of the engine.
