Superman myths.

What people get wrong, and what's actually true.

Many famous Superman 'facts' started outside the comics. He couldn't fly in 1938, kryptonite was invented for radio in 1943, Jimmy Olsen and Perry White began on radio, and the S only came to mean hope in 2003–04. There is no Superman curse. Whether Superman is Jewish-coded is a genuine debate, not a settled fact. And some myths are true: Siegel and Shuster really were paid $130 for the 13 pages of Action Comics #1.

In depth

The full story.

Superman has been around since 1938, which is plenty of time for stories about him to get bent out of shape. We checked 23 claims you’ll see repeated online. Each gets a verdict:

False: it isn’t true.
Misleading: partly true, but usually told wrongly.
Disputed: serious sources disagree.
True: it sounds like a myth, but it isn’t.

Born outside the comics

Some of Superman’s most famous features didn’t start in the comics at all.

#	Claim	Verdict	What’s actually true
1	Superman could always fly	False	In Action Comics #1 (1938) he leaps about an eighth of a mile. Flight came from radio and the Fleischer cartoons (1941), and the comics adopted it around 1943. See flight.
2	Kryptonite was invented in the comics	False	It debuted on radio in “The Meteor from Krypton” (3 June 1943). An unpublished 1940 comic story about “K-Metal” came first but was never printed. See kryptonite.
3	“Truth, justice and the American way” is from Action Comics #1	False	“Truth and justice” came from radio in 1940, and “the American way” was added in September 1942. DC’s motto since 16 October 2021 is “Truth, justice and a better tomorrow”.
4	“Faster than a speeding bullet” is from the first comic	Misleading	The first comic has the express train and the leaping. The bullet wording comes from the radio opening, which earlier said “faster than an airplane” (Likely). See famous quotes.
5	Jimmy Olsen and Perry White were created in the comics	False	Both started on radio: Perry White on 14 February 1940, and Jimmy Olsen was named on 15 April 1940. See Superman’s friends.

The S, the costume and the name

#	Claim	Verdict	What’s actually true
6	The S has always meant hope	False	In 1938 it stood for Superman. The 1978 film made it the family crest, and “hope” comes from Superman: Birthright (2003–04) and Man of Steel (2013). See what the S means.
7	Christopher Reeve says the S means hope in the 1978 film	False	That’s Henry Cavill’s line in Man of Steel (2013). Some quote sites file it under the wrong film (Likely).
8	Superman wears his underwear outside	Misleading	The trunks come from 1930s circus strongman and wrestler costumes. DC dropped them in 2011, brought them back in Action Comics #1000 (2018) and kept them in 2025.
9	Clark Kent was named after Clark Gable and Kent Taylor	True	Joe Shuster said so in an interview shortly before his death (Likely).
10	Christopher Reeve wore a muscle suit	False	He turned one down and trained with Dave Prowse, the Bristol-born actor who played Darth Vader’s body, adding roughly 14 kg of muscle (Likely).

Powers and weaknesses

#	Claim	Verdict	What’s actually true
11	Kryptonite is his only weakness	False	He’s also vulnerable to magic, and he loses his powers without yellow sunlight. See Superman’s weaknesses.
12	All kryptonite is green	False	The comics have many kinds: red (unpredictable effects), gold (permanent loss of powers), blue (harms Bizarro) and more.
13	Superman never kills	False	He executes three Kryptonian criminals in Superman (vol. 2) #22 (1988) and kills Zod in Man of Steel (2013). It’s rare and always treated as a trauma. See the no-kill rule.
14	Superman died and stayed dead	False	The Death of Superman (1992) was followed by his return in “Reign of the Supermen” (1993). See Doomsday.

History and the films

#	Claim	Verdict	What’s actually true
15	Superman was always a hero	Misleading	Jerry Siegel’s 1933 fanzine story “The Reign of the Superman” featured a bald, telepathic villain. The hero came later (Likely).
16	Siegel and Shuster sold Superman for just $130	True, with nuance	DC’s cheque of 1 March 1938 paid $130 for the 13 pages of Action Comics #1, and the same cheque covered other work. Courts later treated it as payment for the pages, not a price for the character. The cheque itself sold for $160,000 in 2012.
17	Superman grew up in Smallville from the start	False	Smallville was first named in the Superboy stories of the late 1940s; the early Superman stories don’t name his hometown (Likely). See Smallville.
18	Superman II is Richard Donner’s film	Misleading	Donner shot much of it alongside the first film but was replaced. Richard Lester completed it and is credited. Superman II: The Richard Donner Cut came out in 2006 (Likely).
19	Nicolas Cage filmed a Superman movie	False	Tim Burton’s Superman Lives was cancelled before filming in 1998. Only costume-test footage exists. Cage did appear as a Superman in a cameo in The Flash (2023).
20	There’s a Superman curse	False	The tragedies of George Reeves (1959) and Christopher Reeve (paralysed in 1995, died in 2004) are real and sad, but a “curse” ignores the many cast members who lived long lives.

Faith and origins: the Disputed claims

These are real debates, so we set out both sides rather than give a verdict of our own.

#	Claim	Verdict	The debate
21	Superman is Jewish	Disputed (in the stories: False)	In the comics he isn’t Jewish; he’s usually raised by Methodist Kansas farmers. His creators were Jewish sons of immigrants, and writers read the immigrant story into him.
22	Superman is a Moses story	Disputed	A baby sent away in a vessel and raised by strangers: writers such as Baskind and Roy Schwartz draw the parallel. Historian Martin Lund argues it’s so general it fits other stories just as well.
23	Kal-El means “voice of God” in Hebrew	Misleading	“El” does mean God in Hebrew, but reading “Kal” as “voice” is a later interpretation, not something Siegel said. Even writers who like the idea admit the spelling doesn’t fit neatly.

Is Superman Jewish-coded? Both sides

The case for: Siegel and Shuster were the Jewish sons of immigrants, writing in the 1930s. Writers including Roy Schwartz (Is Superman Circumcised?) and Baskind read the immigrant experience into his story, and see the baby sent away in a rocket as an echo of Moses.

The case against: historian Martin Lund studied the claim in detail and argues that much of this conventional wisdom doesn’t hold up. The Moses parallels, he says, are general enough to fit Jesus or Sargon just as well, and the evidence that Siegel and Shuster intended them is thin.

Our view: it’s a debate, not a fact. Both readings are worth knowing, and neither is settled.

Era by era.

The same Superman, rewritten for every generation.

Golden Age (1938–1956)

Superman leaps rather than flies in Action Comics #1 (1938). Flight, kryptonite, Jimmy Olsen, Perry White and 'the American way' all arrive through radio and cartoons between 1940 and 1943.

Modern era (2003–)

The S becomes the Kryptonian symbol for hope in Superman: Birthright (2003–04), and Man of Steel (2013) brings that meaning to film.

Questions.

Is Superman Jewish?

In the stories he's raised by Kansas farmers, usually as a Methodist, not as a Jew. But his creators were Jewish sons of immigrants, and writers such as Roy Schwartz read the immigrant and Moses stories into him. Historian Martin Lund argues the parallels are too general to prove. It's a debate, not a fact.

Is there a Superman curse?

No. The story grew from the real tragedies of George Reeves (died 1959) and Christopher Reeve (paralysed 1995, died 2004). It ignores the many cast and crew who lived long, healthy lives. Researchers call it selective memory, not a curse.

Did Nicolas Cage play Superman?

Only briefly. Tim Burton's Superman Lives, with Cage, was cancelled before filming in 1998, and only costume-test footage exists. Cage did appear as a Superman in a cameo in The Flash (2023).
