When Tom Weaver (Grayson McCrouch) is stood by his car checking papers in his briefcase, an older-looking red Valiant car drives slowly by, with the driver staring at him. The valiant & driver's costume strongly suggest it's David Mann (Dennis Weaver) the lead character from Steven Spielberg's 1971 film Duel, in which Mann is pursued by a mysterious big rig truck whose unseen driver is determined to murder him. The use of "Weaver" as Tom's surname in this movie is a similar homage to the original Spielberg concept.
