At the very beginning of the film, when Dell is finally forced to come to a stop by the police chase, Philip's body is seen lurching forward, then leaning back into the seat. But Philip has no muscular control over any part of his body below his neck, so his body should have remained leaning forward, since inertia (the forward motion of the car) would have pushed him into that position due to the sudden stop, and there would be no reverse direction force (no energy coming from either the car or his body).

When Dell attempts to insert the catheter into Philip, he is shown holding a large rubber tube. The tube is too large and floppy to be inserted. A real catheter is much smaller and more rigid.

Physical therapists do not learn to administer catheters, since that task is not a part of their job.

When Dell returns the key of the Alfa Romeo Giulia QV, the close-up shot shows an Alfa Romeo key from earlier models, most likely a Mito or Giulietta. Giulia key fobs look much different.

When Dell and Philip go paragliding, Philip still has his beard. After Dell shaves the beard off, there are more paragliding scenes at the end of the movie. It looks like the first paragliding because the men assisting them are the same guys and everyone is wearing the same clothes and helmets. But this time, Philip has no beard.

When Lacasse is talking about how he had his accident (Dell asked him), he says the weather that day was very bad and there was lightning. But during Lacasse's flashbacks, when he opens his eyes and sees his wife, the sky is clear blue with very little, if any, cloud cover.

At one point the soundtrack plays the Habanera from Carmen. We hear this aria sung in French, but the subtitles say "singing in Italian."
