Film Director:  It is true that certain characters and plot twists in my newly released film The Big Heist are strikingly similar to characters and plot twists in Thieves, a movie that came out last year.  Based on these similarities, the film studio that produced Thieves is now accusing me of taking ideas from that film.  The accusation is clearly without merit.  All production work on The Big Heist was actually completed months before Thieves was released.
 
Which of the following, if true, provides the strongest support for the director's rejection of the accusation?
