Other mistake: During the scenic elevator rescue scene, a helicopter lowers the Fire Chief down to connect a cable to the top of the elevator. The cable is seen to be hanging no more than three feet from the side of the building. If this were the case, the helicopter's rotors would be hitting the building. (02:04:10 - 02:06:10)
Other mistake: When young Vito Corleone shoots Fanucci in the chest at the doorway to his apartment, in a continuous shot, a wound/blood bursts from Fanucci's white vest. When Fanucci proceeds to tear his vest open seemingly in disbelief he has been shot, there is no entry-wound, blood or hole in his white shirt directly under where the wound appeared in his vest.
Other mistake: During the quake, we see the furniture, wall panels, ceiling tile, windowpanes, vertical blinds, etc., in the office fall, shake, or crack. Yet the leaves of a large potted plant do not move at all.
Other mistake: When Sir Anthony Hopkins (playing Johnny McLeod) is awaiting the arrival of the suspected bomber O'Neill (played by Cyril Cusack), a funny mistake occurs. Cusack sees Hopkins, smiles and greets him with a cheerful "Hello, Tony!" instead of "Hello, Johnny!" Being a pro, Hopkins doesn't blink an eye!
Other mistake: At the end when Bond returns to the bedroom after the glass bottle fight with Nik Nak he says "hope you got all the glass out of the bed" but he just walked across the room in bare feet without a care in the world, which was completely covered in broken glass. Goodnight didn't have enough time to clean this up aswell in the time given.
Other mistake: While reading a book in the Hall of Records, Jake notices some names are pasted in. One of the pasted in names is spelled "Clarence Speer." The name comes up again as Jake Gittes and Evelyn Mulwray are driving away from the orchards. The name is spelled in the subtitles "Clarence Speer" and Jake pronounces it "Clarence Speer." Later Jake and Evelyn are reviewing the Mar Vista Rest Home Activities Board. Here the name is spelled "Clarence Speers." (01:07:35 - 01:17:25)
