Continuity mistake: As Harry talks to Murphy from inside the jail cell, his arms are wrapped around two bars with a third bar in the center. When the shot cuts to a wider angle, his arms are no longer draped through the bars: he's instantly standing straighter and holding onto the center bar with both hands. When it cuts back, he's in his original position again. (00:20:05)

Continuity mistake: When Murphy questions her on the park bench, Heather's hair changes repeatedly between takes, from tucked behind her ears to having several strands hanging loose in front of her ears. (00:03:20)
