Toward the end of the film, Kayla (Lynn Collins) is wearing a dress and black tights. In some scenes, the dress extends past the middle of her thighs; in others, it barely covers her rear.

The slip-up occurred when several of the outfits worn by the actors were washed and shrunk during filming. Initially, Collins protested to wearing the shortened dress, feeling it left too much of her body exposed. Director Gavin Hood ultimately persuaded her to wear it for continuity's sake.
