Revealing mistake: When the golden-helmetted Grand Vizier (played by Douglas Wilmer) enters the grotto, to show Sinbad the drawing of the sea chart on the wall, he lights two braziers. As he touches the second one with his burning torch, you can hear a distinct "plop" as the gas ignites.
Revealing mistake: When the fight against Kali starts there's a moving purple area around Kali's feet revealing where the animated footage was pasted.
