Character mistake: We see the lead driving on the motorway to get to the cottage. She leaves at junction 6 for Princes Risborough. Which means she is on the M40 that goes to Birmingham. When she arrives the host asks about the drive down and mentions the M4. This is a different road entirely, that goes to Swansea.
Character mistake: Towards the end of the movie when the Giganotosaurus is attacking the group and Claire gets the rope wrapped around her leg and pulled towards the dinosaur Owen actually shouts Bryce before saving her instead of Claire.
