Erreurs factuelles: Condolences are received from the British "Royal Academy" on the death of Dr. Alistair Barkley. The "Royal Academy" is an Arts institution; perhaps the writers' meant the "Royal Society."

Audio/Video non synchronisé: An actor filmed a scene saying the words "...a disturbance at the Smithsonian" but the words "science museum" were dubbed over Smithsonian instead.

Erreurs factuelles: There is no Amtrak train service to Williams Bay, WI.
Continuité: When Eddie is hanging from the lift at the end of the movie, Lily is supposed to be in the lift. However, one shot shows no one in the lift. At the same time this goof happens, Lily is actually heard saying, "Hold on Eddie!"

Continuité: Eddie is shown running towards the observatory. The dome is clearly closed and the ground is completely covered with snow. There's a quick cutaway to Lily using a laptop before the shot returns to the exterior. Now the dome is open and facing a different direction and there's almost no snow on the ground.
Continuité: In the scene where Eddie and Lily meet Shannon in the museum, they are on the second floor of the Field Museum of Natural History. While running from the guys in the same scene, however, they end up running through the Museum of Science and Industry, and then Eddie exits back through the front of the Field Museum.
