Connor holds an iPad with a picture of a boombox, while it plays music, over his head to get Jayden back, just like John Cusack's character held an actual boombox over his head to get Ione Skye's character back.
When Connor takes Jayden to the movies, "Anderson's Cross" is shown on the theater marquee. Also, director Jerome Elston Scott was also the filmmaker of "Anderson's Cross," his first film as writer, producer, and director.
