When Laurel goes to the buffet at the beginning of the movie she piles the food on her plate. She then knocks the bread on her plate into a different position.In the next scene she is walking back to her table and the bread is piled up again. Between the two shots the bread on the plate moves.
After being cleared to play Danny is shown at the team practice (approximately 1:35 into the movie). He is wearing a regular blue jersey. Quarterbacks always wear a different colored jersey (usually red) to ensure they are not hit or injured at practice. This would be specially true of a QB first returning from an injury.
Laurel tells Danny her Mustang is a '65. It is not. In 1967, Ford produced the first redesigned Mustang. One of the changes were concave tail lights.
Laurel unlocks her driver side door with a key, but Danny opens his side before Laurel can unlock his side.
When Danny calls his dog for Laural to walk, a dog leash is visible being let go right before the dog runs out and knocks over Laura.
An aerial establishing shot of where the football practice is happening shows it as BC Place (in downtown Vancouver), a huge indoor stadium. When they cut to the actual practice, they are at the much smaller outdoor Thunderbird Stadium (at the University of British Columbia, in a very different part of the city). When they walk out of the stadium into the parking lot after the practice, they are back outside BC Place.
Laurel says her car is a 1965. The Ford Mustang she is driving is a 1968 model as evidenced by the concave tail lights and side marker lights.
