Corrected entry: In the scene when the two kids find Peter's overturned wrecked car on the beach, the right front tire is missing. When the car landed in the water, all four tires were present.
Corrected entry: When Jim wakes up on the beach, the sun is high up in the sky and very bright out as seen from the short shadows cast and him squinting. He and the old man then walk a ways to the town, and then Jim states how quiet it is, and the man states that it is still very early in the morning and not a lot of people are up. Therefore if he was found at say noontime by the man and dog, then it would have been much later when they got to town.
Corrected entry: When the theatre opens, we get to see the announcements of the films that are being shown. There are "An American in Paris" "A streetcar named Desire" and of course "Sandpirates of the Sahara". However, the slate above the ticketbooth also announces "Invasion of the bodysnatchers" being shown. Al these films are released in 1951, except for the last one. "Invasion of the bodysnatchers", according to www.imdb.com, was released 1956.
Corrected entry: At the begining of the movie Jim Carrey, as Peter Appleton, is at the theater in L.A. and with consessions in hand he stops and cleans the glass over the movie poster that has his name on it at the bottom as "written by...". When they show his name the poster number 51/346 is visible at the bottom meaning this was poster number 51 out of 346 posters. Later in the movie and several months into the plot when he is at the Majestic theater and the Sand Pirates movie is playing and he suddenly remembers who he is and runs to the lobby and looks at the bottom of the poster to find his name the poster has the very same number..51/346. I doubt that the L.A. theater would have folded up the poster and sent it to this small town in northern California. Most theaters kept the posters or gave them away.
Corrected entry: When Peter Appleton leaves the studio, his place of employment, a view of the famous 'Hollywood Sign' is in the background. This film is set in 1947, the year of the well-known Hollywood Blacklist and HUAC hearings. Until 1949, the Hollywood Sign actually read 'Hollywoodland,' created as an advertisement for the orignal real estate development with the aforementioned name.
