All About Steve (2009)

Continuity mistake: When the crane breaks, it only drops one end of the cable with the hook into the hole. However, later on Mary makes a contraption which the cable snapped and both ends are in the hole, going up over the pulley on the crane. The number of cables going into the hole from the crane varies for the remainder of the movie from 1 to 2 cables - and is not to be confused with the string of lights.
