When Thaddeus Bradley is explaining to Dylan Rhodes and Alma Dray how he began his career exposing magicians, the camera cuts to Rhodes twice. However, both cuts are exactly the same. All three characters are seated at a table. At different points during the scene, two ladies are seen passing each other on a set of stairs just behind Rhodes' as he tilts his head to listen more intently to Bradley's story. The same cut is used twice.
