Love Ranch starts out in 1976, but the Reno Arch shown in the beginning of the film is the third Reno gateway and was not erected until 1987.
At the beginning of the film, Charlie and the band are performing to a packed house. The drummer uses a crash cymbal from the very popular Zildjian company, the A Custom. This movie takes place in 1976, and the Zildjian A Custom didn't come out until 1990.
After Grace kicks Bruza out of her car, she drives to his trailer park where we see a small satellite dish attached to one of the trailers, but mini dishes weren't used by private residences in 1976.
The Pontiac Firebird that Armando drives is a model that was not released until 1979.
During lasso scene at Second and Virginia Street the intersection shows Grace stopped and next to her is a Reno Police Van with a Nevada Highway Patrol license plate. It should say Reno Police on the license plate. Nevada DMV prints the law Enforcement Agency on the license plates used by that agency.
The "Boxing Gym" is a military surplus store.
Bruza tells Grace "I've come to suck your blood", like it's his impression of Bela Lugosi as Dracula. Lugosi never said anything of the kind. This is a common mistake.
Grace incorrectly refers to the Frankenstein Monster simply as Frankenstein, the name of the scientist who created the monster. This is a common mistake.
