When Charlie writes on his whiteboard in his office, the three P's at the top of the board change shape between shots.
Molly's bloody nose disappears during the attack in her apartment.
During Molly's second visit to Charlie's office, her top goes from symmetrically positioned on her body to off the shoulder between shots.
During Molly's arraignment, when her and Charlie are walking over to their seats Molly is seen untying her waist belt and undoing her coat button, in the following scene she is seen with her coat opened, and just before she sits down she is seen untying and undoing her coat belt and button again.
There are abrupt changes in Molly's clothing over her right shoulder in between screen shots while she is discussing her case with her lawyer (sweater on her shoulder and then off her shoulder among other continuity errors).
The house can't decide to take a rake (cut of the pot) in the middle of a poker hand. The players would revolt. A rake must be established with some advance notice. It's usually in force before any play begins.
In one game, the initial bet is $300,000 and the second bettor raises the bet by $200,000. That wouldn't be allowed in any poker game. A re-raise must be at least as much the original bet. In this case, the minimum re-raise would have to be $300,000.
In the movie, Molly says the pitch of the mogul run at Deer Valley is 52 degrees, which is the same as the Great Pyramid. While the side of the Great Pyramid has a slope angle of 51.4 degrees, the course angle of the Deer Valley mogul run is 28 degrees, which corresponds to an average slope *grade* of 53% (percent, not degrees).
Molly says that Harlan Eustice plays "tight" because he folds after the hole cards 64% of the time. This is NOT tight. A good player will fold about 80% before the Flop and a "tight" player will fold even more......as much as 85% of the time or higher.
Molly states at the end of the movie that she will never be allowed to vote again. It depends on in what state one resides whether that person is allowed to vote with a felony record. If she chooses to live in New York or Colorado, she can vote.
When her father takes Molly's pulse at the ice rink he uses his thumb, which should not be considered a character error: while doctors and paramedics are taught to use the index and middle fingers, her father is in a position where it is easier to use his thumb and he must have done it many times to check her heart rate.
Molly's lawyer reads a published copy of the book Molly's Game to research her defense. In real life, the book was published after the trial was over.
In a scene set in 2003, a woman can be seen smoking a cigarette inside a Hollywood nightclub. However, California banned smoking statewide inside bars and nightclubs clubs in 1998.
When Molly recalls moving to New York, the city skyline is shown. This is supposed to represent New York in 2010 or before, but it shows the Freedom Tower complete with its spire. The tower was topped off in 2012 and the spire placed in 2013.
The Dynastar Twister skis that are in the background of start tent at Deer Valley were 2015 model year graphics.
The K2 244's that Molly was skiing were not introduced until about 2010 and the Rossignol FKS 120's were also even newer models.
The ice skates sliding on the ice do not make this very inaccurate dubbed noise.
In the final court room scene, the camera marks for Molly and Charlie are visible under the table.
In the opening voiceover, Molly states she is from Loveland, CO, two hours north of Denver. Loveland is about 45 minutes north. Two hours would get you to Cheyenne, WY.
When Player X suggests raising the buy-in from $100K to $500K, Molly remarks that that would be a 500% increase. It's 500% as much money, but only a 400% increase.
Brad says "I'm no card shark." This is a common mistake based on the terms 'card sharp' and 'loan shark'.
