Other mistake: Cliff's dog is referred to as female but when it jumps up at a door towards the end of the film, it is male.
Other mistake: When Cliff fights Bruce Lee the doors are already dented before Bruce gets tossed into them.
Other mistake: Rick Dalton's Cadillac has a badly worn steering wheel. In 1969, the car was not old enough to have had that much wear. It should have been painted.
Other mistake: George is blind but when talking to Cliff and telling Cliff he is touched that he came by to visit, George hits Cliff's left shoulder with his fist, a nice direct hit.
Other mistake: When he puts the 2nd can of dog in the bowl it's just a rerun of the 1st can being dropped in a bowl.
Other mistake: Over a car radio, KHJ's Robert W. Morgan is heard giving the weather forecast. The predicted high is "95 downtown, 105 in the valley." The scene takes place in the middle of winter, February 9, 1969.
Suggested correction: The daytime temperatures can reach that high in the winter.
The highest recorded temp for Feb 9 for Downtown LA is 89 set in 2016, and the highest February temperature ever there was 95 on Feb 20, 1995. "The valley" is too ambiguous to identify where it means. So while they "can", they don't, and any movie showing record-setting temps during winter, even if theoretically possible, would be considered wrong.
Other mistake: When Cliff picks up Pussycat off the street, he mentions about picking her up on Burbank Blvd to take her to Chatsworth. This entire route would start and end in the San Fernando Valley, but when the journey begins, they enter the 101 freeway from Hollywood Blvd (nearly 10 miles away from anywhere near the route).
