====''Superman Returns''====
The 2006 film ''[[Superman Returns]]'' presents a version of Krypton almost identical to [[Superman (1978 film)|''Superman'']]. In the beginning of the film, scientists discover remains of Krypton, and Superman leaves Earth for five years to look for it. His ship is seen leaving the dead planet. The planet is destroyed when the [[red supergiant]] Rao becomes a [[supernova]].

''Superman Returns'' extends the [[crystalline]] Kryptonian technology from ''Superman'' which allowed young Clark Kent to "grow" the [[Fortress of Solitude]]. Kryptonian crystals are able to grow huge land masses and incorporate the properties of the surrounding environment; a sliver taken from one of the crystals used to test the theory causes Lex Luthor's basement to be filled with a huge crystal structure. Growing land in this manner causes widespread power failure. Lex Luthor later combines one of the crystals with kryptonite and shoots it into the ocean, creating a new land mass he calls "New Krypton". Superman uses his heat vision to get under the crust of the island and throws it into space, including the other crystals that Luthor wanted to use to set up a real estate scam, despite the warning that many people would die from the massive tsunamis and earthquakes that the crystals would create.

The novelization by [[Marv Wolfman]] states that one of Superman's ancestors helped civilize Krypton long ago.
