Diana exits to the parking lot in the beginning of the episode to pick up the dropped picture, and the older couple/parked white car in the background disappear between shots.
The first ambassador is handed three photographs and drops one outside the car. In the car, he still has three photographs in long shots but only two in close-ups.
Diana's glass at the reception is less than half-full from the front. The next shot, over her shoulder, shows the cup to be much fuller.
Diana rolls down a hill and transforms into Wonder Woman, but her roll is the wrong direction to trigger the transformation.
Diana falls through the trapdoor and lands in the pit, clearly wearing black ballet flats. In the next shot, she has on 3-inch black heels.
IRAC refers to Steve as Major Trevor, but Steve Trevor, Jr. has the rank of lieutenant colonel.
