In the [[Superman (1978 film)|first feature-length ''Superman'' film]] in 1978, a vastly less idyllic image of Krypton was presented. Whereas in the comics Krypton was colorful and bright, the film depicted the planet with stark bluish-white terrain of jagged frozen plateaus under heavy, dark skies. The planet was threatened by their sun turning into a [[supernova]]. [[Jor-El]] unsuccessfully attempted to persuade the council of elders to immediately evacuate the planet.

Kryptonians themselves were portrayed as coolly cerebral and morally enlightened, clad in stark white bodysuits emblazoned with each family's house symbol. The architecture featured halls of white crystal under crystalline arches. The crystalline motif was employed not only in the architecture, but in the landscape and technology as well, suggesting that the entire planet had been adapted and altered by Kryptonian influence. In 1948, Krypton was ultimately destroyed when its red sun began to collapse; the planet was pulled into the sun and steadily crushed, then exploded in the ensuing supernova. When Krypton was destroyed, fragments from the planet were launched into space, resulting in the creation of a harmful radioactive substance known as kryptonite.

Both Jor-El and Lara preserved some part of their "essence" (in the form of virtual copies of themselves) in the starship that took three years to bring their child to Earth. On [[Clark Kent]]'s eighteenth birthday, a glowing crystal revealed itself in the ship and compelled Clark to take it north. He eventually reached the [[Arctic]], where the crystal constructed the massive crystalline Fortress of Solitude. Inside, an [[artificial intelligence|artificially intelligent]] hologram of Jor-El appeared to him and initiated twelve years of Kryptonian education. These virtual versions of Jor-El and Lara remained as constructs within the Fortress throughout the series.

Superman's symbol was given a Kryptonian origin in the film. Male Kryptonians were shown wearing unique symbols on the chests of their robes, similar to a [[coat of arms|family crest]]; Jor-El and Kal-El wore the familiar S-shield, which [[Lois Lane]] later assumed to be the letter ''S'' from the familiar [[Latin alphabet]], and thus dubs him "Superman".
