When Xiulan is being scolded by Auntie Blossom for teaching the other girls English, Xiulan's hair moves from her side to in front of her chest to back to her side again over the course of the conversation.

The film's portrayal of Wong Jack Man contains numerous factual errors. The biggest being that he was not a Shaolin monk and he didn't come to San Francisco as penance for nearly killing a man in a duel. Also he didn't return to China afterwards since he continued to teach martial arts in the Fort Mason Center of San Francisco until he retired in 2005.

The movie depicts Lee's school as being in San Francisco when at the time it was across the bay in Oakland, CA.

The movie falsely has Lee working on a martial arts film starring himself to boost his profile. At this time in his life Lee, who had starred in 20 films in Hong Kong before coming to the US, had given up acting to concentrate on his Martial Arts studies.

Wong Jack-man is shown as coming from Mainland China. In fact he was born in Hong Kong.

Had he been a citizen of the People's Republic, he could not have entered the USA in 1964. It was only in the 1970s that the USA recognised it as a legitimate state.

The term "chopsocky" used by one of the gangsters in the final fight wasn't coined until 1974 in a Variety magazine article on the explosion of kung fu films in the US.
