In the preliminary round game between the Long Bay and Butte rinks, the rock that Cutter throws that eventually gets burned by the sweeper travels down the right side of sheet as he throws it. The portal that he is aiming for and which the rock eventually goes through is on the left side of the sheet.

The score on the scoreboard changes inconsistently between shots during the Long Bay/Butte game.

Throughout many of the games you will see that there are many rocks left in the house. The true way of counting score in curling is whoever has the closet rock to the button gets 1 point, then for every other rock that is closer gets another point until an opponent's rock is closer then any more in the house. During many of the games some houses were left with up to 5 rocks in the house with no opposing rocks. The scores should have been much higher in all the games, most notably in the final game.

Paul Cutter's moral dilemma as a cheater is entirely contrary to the rules of curling. Canadian and world curling rules require players to call their own infractions. In the situations depicted in the film, "burning" a moving stone is an infraction by the sweepers, not the player delivering the stone. It's the responsibility of the front end, never up to Cutter, to call the burned stones.

In the championship game between the Long Bay and Butte rinks, Long Bay would not have had the last rock advantage in the final end as it is portrayed, as the rules have the last rock advantage going to the team that did not score in the most recent end in which a team did score. As such, Butte should have had last rock advantage in that final end.
