Character mistake: As Lex is studying the recording of when Superman's body vanishes, he says "A 19 second black out at 3:47 AM." But the clock on the video shows it goes from 3:47:05 when the blackout starts, to 3:47:26. The blackout was 21 seconds, not 19. (00:45:55)

1 character mistake
Directed by: Lauren Montgomery, Brandon Vietti, Bruce Timm, Bruce W. Timm
Starring: John DiMaggio, Adam Baldwin, Anne Heche, James Marsters
Continuity mistake: In Metropolis on the bridge, Doomsday grabs a soldier and breaks his neck and skull. In that shot, the soldier's arms are inside Doomsday's hand and his hair is a light brown or gray. But then when the shot changes as Doomsday begins to throw the soldier to the side, the soldier's arms are suddenly outside of Doomsday's hand, and his hair is now black. (00:17:10)
Grumpy Man: Yeah, like we really needed him to bust up the mechanical spider, right? Lame.
More trivia for Superman/Doomsday
Question: So how exactly did Doomsday's ship get buried so deep? On the movie the Project Apple Core workers say they discover it's "before Christ deep", but don't specify exactly how old. And they are 2 miles down at the time. Lex Luthor interprets the alien hologram as a warning and says that an alien race must have trapped Doomsday here because they could not kill it. And later the robot at the Fortress of Solitude identifies Doomsday and tells Superman what it is. I know there are several differences between the film and the comics it's based on. Are there differences in how Doomsday got there and how is it so deep?
Answer: In the comic book, Doomsday was put in a strait-jacket, strapped in metal bondage and placed in a cube like metal prison buried deep in the earth. It took him centuries just to break the bonds, then spent more centuries just punching his way out. With earthquakes, volcanoes and other natural disasters those events could shift Doomsday's prison to the surface.
