Factual error: As someone already noted, the Boeing 747 didn't enter commercial service until 1970. In addition, the Pan Am 747 type shown flying the characters back to the U.S. never existed. It has the extended upper deck common to the 747-300 and -400 series (introduced in the 1980's) but with only three windows (common to some -100 and -200 types). Also it has higher bypass engines which came later.Verbal
Factual error: The Cielo address is mentioned in the movie as being in Hollywood. It was actually in the Benedict Canyon section of Beverly Hills, several miles away from Hollywood.

Factual error: Most of the eyewear used has anti glare coating on the lenses, not used until the early 80's.

Factual error: In the beginning of the film, an aerial shot shows Cliff and Rick pulling out of a studio parking lot. The lines in the lot are yellow double lines between spaces. They didn't use that type of striping in parking lots in the 1960's. The parking lot striping was white with single stripes in between spaces.
