In the new Zack Snyder movie "Batman v Superman"
Superman sacrifices himself in order to kill Doomsday
The end of the movie leaves us wondering if he will return, with a bit of a "inception"-like last scene. The question is:
Will Superman be part of the Justice League in the upcoming movie, or is/was his casting just a ruse to suprise people with his demise in "Batman v Superman"?
Is Superman really dead?
Is there any storyline in the comics, where
he returns from the dead?
(I tried to keep this question as spoiler-hidden as possible)
