Trivia: The planet where Jyn is being transported to the Imperial Labor Camp is called Wobani - an anagram for Obi-Wan. (00:12:20)
Trivia: When Mr. Jimmy is calling out names on the boat to see who's missing, the real Mr. Jimmy Harrell is standing next to him, wearing a dirty grey T-shirt (and presumably playing a random rig worker). You can first see him (from the back) when Russell calls out Caleb Holloway's name. The first view of his face is just as Russell gets out the life raft onto the deck of the rescue ship. (01:28:30)
Trivia: James McAvoy was frustrated in filming a scene with the multiple personalities talking amongst each other, and he punched a door that broke his knuckle. McAvoy filmed for three days without telling anyone and his swollen hand can be seen in this scene.
Trivia: Captain Vincent Peter Lombardi, skipper of the New York Riverways ferry Thomas Jefferson, plays himself in the film. (00:49:24 - 01:34:40)
Trivia: While eating breakfast there are "letters" on the window ledge in front of Ed and Lorraine at their home. They spell out the word Valak, the name of the demon they encounter once they are in England. (00:30:30 - 00:32:00)
Trivia: During the big fight between Batman and Superman, a broken window has the same shape as Ontario, in Canada. Superman creator Joel Shuster was born in Toronto. The broken window is only ever shown from Superman's angle, not Batman's. This was confirmed by Zack Snyder as being a deliberate, if obscure, easter egg.
Trivia: The corpse of Sid Shattuck, which Ryan Gosling discovers after his drunken roll down the hill, is played by an uncredited Robert Downey Jr., who'd previously starred in Shane Black's "Kiss Kiss Bang Bang", a film which played a large part in revitalising his career after drug and legal issues.
Trivia: After Tony blows off Bucky's arm, Cap picks up his shield and shields himself from Tony's blasts. At the very end of the shot, Tony is firing a beam at Cap which lands on Cap's shield and the shot begins to slow down. This moment from the shot is an homage to the cover from part 7 of the Marvel Civil War comic storyline, where Captain America and Iron Man are fighting on the front cover in the same way. (02:07:00)
