Continuity: Supergirl's bracelet swaps wrists while she's flying at night.

Continuity: When Selena is holding the glass champagne and says "I can't wait 'till the world is mine", from a back shot her finger is below liquid level, in the following shot it is above it.

Revealing: When Selena uses her magical powers to accelerate the fairground ride to superfast speed, the twinkling fairground lights in the background are also flashing much faster. They obviously played the tape back at high speed to achieve this.

Continuity: After Lucy leaves out for the weekend, while Supergirl is sitting on the grass, the people standing by the red car behind disappear between one shot and the other.

Continuity: Inside the girl's bathroom, when the red haired girl comes running in with her friend, watch the towel in the back: In one shot it's laying messy on the sink, and a second later it's neatly folded.

Continuity: Supergirl crushes a rock and gets dirt all over the sleeve of her suit. A second later dirt is gone and the suit is clean.

Continuity: At Selena's party, while Nigel is talking to the blonde girl, the green straw in his cocktail moves around between shots.

Continuity: At the end, when Ethan is saying goodbye, in the wide shot there's barely no one behind the red car on the left. In the close shot a lot of people appear.

Revealing: When the invisible monsters throws Supergirl against the street light, the place she falls looks uneven with the rest of the lawn, and is filled with chunks of grass to hide the landing mat. In a wider shot all this atrezzo disappears.

Continuity: When Selena makes a toast with Ethan, from the front the logo and name of the beer is visible, in the following shot it's not.
