This could just as easily have been based on the Scruffy Murphy's pub sting in Dublin thirty years ago. The Irish national lottery had a rollover jackpot of 1.6 mill ( plus additional bonuses ). 20 or so people put their thinking caps on and realized that 900k worth of tickets would guarantee a jacket win, and and the considerable amount of bonus payments that went with it. As in this movie, hours were spent filling in every ticket, and sure enough, a handsome profit was made. It's a story that's still told to this day, and the Irish lottery responded to these events my adding an extra number to make sure it wouldn't happen again. Art imitating life :)
