Continuity mistake: Once Jimmy sees Lois outside the Nite Club, he comments on what she is wearing. In the first shot, he has the strap of his camera around his neck and down his chest. It cuts to a close up as he makes his remark and suddenly the strap is gone. Then in the next shot after Lois grabs him by his earring, the strap is back, but only over one shoulder. Also in the shot where the strap vanishes, the people around him instantly change around. (00:44:30)

Continuity mistake: Jimmy picks up the newspaper Lois hands him and sees the picture of Lex and Superman together. He says "Okay weird." Then the camera changes angles and now the shapes on the back of the paper are a little different, most notably the large box next to Jimmy's right hand vanishes. (00:45:25)

And now the pipes are not bending to go straight down but diagonally to the left towards a machine. (00:46:15)
Continuity mistake: When Superman first wakes up back at the Fortress of Solitude after his body is recovered by his robot, the first thing be sees is the robot looking down at him. In that shot, the 4 lines that form the robot's mouth are much thicker than any time before, and they are unevenly spaced and shaped. (00:47:10)
Continuity mistake: After Superman wakes up and sees the robot reviving him, the camera pulls back to a far shot to show him on an operating table with a machine beside him on each side, and a board with digital display behind the robot. When it cuts to Superman's perspective of the robot, the machine to his left changes shape some, and the display on the board is a little different, most noticeably the part in the bottom middle has a pointed corner instead of a cut off corner.

Then when the camera shows a high angle of the vehicle with the dead Toyman on it, the blood is gone once again. (00:49:10)
Continuity mistake: When Lois pushes her way through a crowed to see where Toyman was killed, she pushes buy a blond guy with a camera that has a badge like thing attached to his shirt, my guess is a press pass.

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.
