Thunderball (1965) - 7 major mistakes

Continuity: When James Bond is fighting underwater with an opponent, the opponent rips off James' diving mask (which is blue). Then James rips another mask off another opponent who is lying dead on the ocean floor. This dead opponent's mask is black. James puts on the black mask and then he turns around and the mask is blue again.

Continuity: When Bond and Domino are walking along the beach in shallow water, Domino stands on a poison quill spine with her right foot. But when is Bond sucking the poison out, he does so from her left foot.

Revealing: During the fight at the beginning of the film, if watch it slow motion, you can that poker that is being used to strike Bond is not made of metal, it bends when the blows are being aimed.

Other: When Bond and that girl are floating at the end right after the boat crashed, the bottom of the ocean looks very shallow and very much like the bottom of a pool.

Continuity: When Domino is on the beach with 007 she is given a dog tag belonging to her deceased brother, in one shot she has both hands on the tag and moves her right arm to the sandy floor but midway through a sentence the shot turns to a different angle where she has both arms on the tag again.

Revealing: When James Bond and Felix have found the missing plane, look at the colour of the water as the helicopter lands, it is evident that is landing in shallow water, (they are supposed to be in much deeper water with sharks swimming below them) you can see the sand below. If the helicopter had landed on deeper water, the water colour would be dark blue.

Revealing: When the plane being piloted by the traitor crashes into the water, during the time while it's skidding across the surface and especially when it stops, you can see a large black wire attached to the middle of it and going into the "sky".
