In the first game Guru Pitka hits Darren on the head with a stick of yellow flowers (right after he tells him he is not allowed to fight with anyone). Most of the petals fall off. When the camera cuts back as the Guru turns to his assistant the stick is full of petals again as before.
In Coach Cherkov's office the ceiling tile around Pitka's head suddenly rotates forty-five degrees before he leaves.

During the first game between Toronto and LA, Roanoke and Grande get into a fight. The referee informs Roanoke that he has been suspended. Referees cannot suspend players from future contests, and would order a game misconduct in this situation.
During one of the Stanley Cup games Roanoke hits the puck
above his head. He then hits the puck out of the air while it is at head level and scores a goal. This goal would have been disallowed since a player is not allowed to touch a puck with his stick if it is above the normal shoulder height. This infraction is called "high sticking the puck".
When Coach is asked to stall, he calls a time out. The play by play commentator reports Toronto taking its "last" time out. This implies they have multiple time outs. In the NHL, a team is only allowed ONE time out per game. The same error occurs later on, the coach is asked to stall again to which he replies "We're out of time outs" and then fakes a heart attack.
In hockey the last minute of each period is counted down by tenths of second not whole seconds. Each and every time a game clock is shown in the last minute of play is counts down be seconds.
The movie depicts the teams wearing the 2007 version of the Stanley Cup Finals badging on the chests of the jerseys, however the teams are wearing the RBK Edge styled jerseys that were introduced for the 2007-08 season, the badging is wrong with the jersey styles.
When Cherkov hits Pitka in the genitals, Pitka should not react with pain considering he is wearing a chastity belt. However, Pitka's quick recovery from the injury shows that he is just acting for the crowd to conceal the belt's existence, due to embarrassment over having to wear it. Cherkov can also be seen as reacting in surprised pain, shaking his hand while Pitka collapses.
Underneath the movie's title, the Roman numeral depicting the movie's copyright release year is incorrect. It is written as "MXVIII" which translates to the year 1018, and not the correct number for the movie's release year of 2008, which is "MMVIII".
Guru Tugginmypudha's defining feature are his eyes which are said to be permanently crossed, yet while he's pouring tea through his nose, Ben Kingsley clearly uncrosses his eyes for a few seconds before catching himself and recrossing them.
Rob Huebel (who played Frat Guy during a bar fight scene) is credited incorrectly in the end credits as Ron Huebel.
During the scene where the Guru Pitka is talking to Darren Roanoke at Niagara Falls, the two are seen standing at the lookout next to the Bridal Veil falls.

It is mentioned that Roanoke lives an hour from Toronto. However, it is closer to a two hour drive to the border.
