Encino Man (1992)

Continuity mistake: During the driver's ed part, in one scene the main character, Dave, is in the back seat and in the next, a double is there in his place. You can see the double's face as plain as day and he has a big smile on his face.

Stoney: Far too much responsibility for me, anyways, I'm already popular.
Dave: Yeah, you travel in large groups of one, Stoney.

Trivia: Although this movie is titled "Encino Man", none of it was filmed in Encino. The Morgan house was filmed in West Hills, CA (around 13 miles from Encino), and the school was filmed in Sylmar, CA (around 15 miles from Encino).

Question: This film was called California man in the UK, I'm guessing the reason it was changed was because the UK wouldn't know what Encino man meant, which (in my case) is true. What does Encino man mean?
