In the baseball game scene, Michael Rezendes, Sacha Pfeiffer, and Walter Robinson can be seen in the background.
Walter Robinson said of Michael Keaton, "It is like watching yourself in a mirror, yet having no control of the mirror image."
During an interview on National Public Radio's "Fresh Air", director Tom McCarthy said that they built a large set to depict many of the Boston Globe offices, where parts of the story take place. When the reporters depicted in the movie first visited the set, they gravitated to "their" desks, and many of them started to arrange the items on those desks the way they had been at the time.
When Michael Keaton accepted the role, he had tracked Walter Robinson before meeting him, and found out he lived near Robinson's house. He had also gotten hold of video and audio of Robinson. When Keaton first met him, he did an impression of him that was so impressive, that Robinson was scared, and said to him, "How did you know everything about me? We just met."
As of the film's release, Michael Rezendes was the only journalist involved in the investigation still working on the Spotlight team.
