Factual error: In scenes that take place in 1912 on the porch of the hotel you can sometimes see American flags in the background. The flags in the movie have 50 stars. The 50 star flag wasn't adopted until after 1959.

Continuity: When Richard discovers the old registration book in the hotel attic, he appears to find his signature on the left hand page. When, in 1912, he actually signs the register, he signs on the right hand page. Strangely, the pen and inkwell are located to the left of the register, which would be inconvenient for all but left-handed customers.

Continuity: When Reeves signs the guest register at the hotel in 1912, his signature is different from the one that he saw in the register that he found in the attic.
