Visible crew/equipment: When Rick returns to his caravan after he made a bad impression on the set, as he blames himself for not be able to remember the lines and saying: "You seemed like a f****ng baboon" a shadow of someone moving appears for an instant on the board of the table in front of him on left side of the screen.
Visible crew/equipment: In the scene where Cliff's tire gets slashed at Spawn Ranch, and he punches the hippie, crew can be seen in the horse corral behind Cliff in the background. The crew can be seen 3 times.
Answer: Yes, though the intention was not Tarantino's. What is onscreen is the trailer of the (real) 1970 film "C.C. and Company", which starred (as you might have guessed) Joe Namath and Ann-Margret. Said trailer showed their names twice, a stylistic choice that emphasized the film's stars, and Tarantino used the unaltered trailer in the film.
