Superman (1978) - 145 mistakes

Revealing: All the footage of the missiles being launched is of a poor quality and grainy, which is inconsistent with the good quality of the rest of the shots, revealing that it's stock footage.

Continuity: In the extended edition, before Superman enters Lex's lair his hair is short, then when he's being shot at, his hair is much longer and bulkier. When he finally enters the place, it's back to short.

Revealing: Superman has just saved Jimmy at the dam and is holding him in the air. Jimmy's fringe is standing up thanks to some hair fixer to achieve the effect of wind blowing (though it's a green screen effect). When Superman sets him on the floor his hair remains up giving away the trick, until the angle changes and it looks all combed and nice.

Revealing: Superman has fillings in his teeth.

Revealing: When Jor-El is placing the baby Kal-El into the spacecraft, you can see his Rolex under his sleeve.

Visible crew/equipment: Just after young Clark Kent jumps in front of the train, there is a close up of the train speeding by with a very visible camera in its reflection.

Continuity: Kal-El's cradle arrives on earth, flies zooming past the Kents' car, which is driving in the opposite direction and crashes 500 meters behind the vehicle. The car keeps moving for about 200 meters and then pulls over. A brief shot shows an intact curb on the right. However, when Jonathan Kent gets out of the car, everything changes: The cradle has moved 700 meters and lays next to the car; and the immaculate field is now destroyed by a huge ditch.

Visible crew/equipment: Near the beginning when Lois and Clark are walking out of the Daily Planet, Clark gets stuck in the revolving doors. But, look closely at the glass door, and you can see the crewman holding the door so that Christopher Reeve can get stuck.

Continuity: The lights on the heliport keep swapping from facing the ground to pointing at the sky between shots.

Audio problem: In the plane, when the Captain says "I'm not too god, what do you think" his lips aren't moving.

Continuity: On the Golden Gate, the blue beetle skids and stops with the rear tyres on top of a painted white line. A frame later the car is on the middle on the white line.

Continuity: Inside the cab arriving at the Daily Planet, the fruit stall has no van behind. Immediately afterwards, a van appears.

Continuity: When Otis is reading the paper about the meteorite found in Addis Ababa, the amount of chocolate in the candy bar increases or decreases depending on the shot.

Continuity: The telephone poles close to the gap on the railroad disappear in the wide angles.

Revealing: When Lois is at the heliport, watch the wind flag on the left: when the helicopter arrives, the roaring wind from the vanes makes the flag move up and get stiff. In the close-ups, you keep on hearing the sound but the vanes are off screen. Watch and you'll see the wind flag is down, thus revealing that the engine is off and that the sound we are hearing is fake.

Continuity: When leaving the Daily Planet for the first time together Clark gets stuck in the revolving door behind Lois. He lets her go through ahead of him and gets in the next section as the door revolves. Cut to the exterior of the Planet when they emerge (just before they meet Rex Reed) and Clark is in the same section of the revolving door as Lois.

Other: When the camera pulls back from Superman in his Fortress of Solitude, right after the image of his father wanting to hug him disappears, you can see on the right of the screen that one of Superman's 'crystal' walls is fluttering or shaking like it's made of plastic.

Revealing: In the final shot of the destruction of Krypton several of the people falling into the abyss disappear a split second before the shot of Krypton exploding.

Continuity: Liz places her kitty on her right shoulder and on the next shot the cat's gone.

Continuity: When Luthor switches the snow machine off, a wide angle shows the chamber totally covered in snow and ice, but the close-up of the vents and the walls surrounding are spotless.
