The Batman

Robert Pattinson's audition/screentest took place while he was in rehearsals for shooting Tenet (2020) in Los Angeles in May 2019. Pattinson had to lie to Christopher Nolan about it, but Nolan, who was no stranger to Batman and Warner Bros., immediately figured it out. Pattinson: "I said I had a family emergency. And as soon as I said it, he goes: 'You're doing the Batman audition, aren't you?'" When Pattinson was told that he won the role of Batman a day before principal photography for Tenet began, he was surprised that Nolan also knew and congratulated him, although Pattinson hadn't told anybody about it yet.

As a rule, forensics analysts don't just plug digital media straight into their computer. For one, it becomes inadmissible in court since it can argued maybe the cops put incriminating evidence on the drive. The other thing is it might trigger a logic bomb which is exactly what happens when Gordon pulls up the pictures on the "thumb" drive. In reality, the drive would go to the lab and be imaged for a copy that would then be looked through. A detective as seasoned as Gordon would know better.

After the credits finish, a final message from Riddler appears through a computer terminal screen that says "GOOD BYE ?" followed by a quick flash of Riddler's URL that is featured in the movie.
