Factual error: When Judy gets home and the key isn't working she looks at her iPhone and sees a long list of calls to Steve's mobile phone. This is wrong. IPhone just shows the name once per day and the number of calls in between brackets.
Continuity mistake: When they're all releasing the balloons the shot from behind shows no wind moving the balloons; a shot later from the front there's a very strong wind; but a shot later from a side angle there's now a mild breeze blowing.
Continuity mistake: When Judy wakes up with Steve, her left arm is either tucked under the sheet or on top of it, depending on the shot. This changes back and forth.
Continuity mistake: When Judy is watching Nick sign at the Carry On-oke an Asian guy with a striped shirt behind her appears / disappears between shots.
Plot hole: Judy takes all of the money out of the joint account, but then has no money for a place to stay?
