'' in which Columbo first appears, depicted by
Bert Freed Columbo first appeared in a 1960 episode of
The Chevy Mystery Show titled "Enough Rope", wherein he was portrayed by
Bert Freed. After this, the character was portrayed almost invariably by
Peter Falk, who appeared in the role from 1968 through 2003.
Roger Ebert speculated that Columbo's character was also influenced by Inspector
Fichet from the French suspense-thriller film
Les Diaboliques. Columbo's signature
catchphrase, "just one more thing", originated when Levinson and Link were writing a scene in which Columbo interrogated a criminal before leaving his apartment. The scene was too short, however, and they could not add conversation into the middle of the scene as they were using a typewriter, and that would require rewriting the scene from the beginning. They decided to fix this by having Columbo stick his head back through the door and say "just one more thing" as if he had forgotten something. Due to Columbo's first name being obscure in the show, author Fred L. Worth intentionally included a
fictitious entry in
The Trivia Encyclopedia, falsely claiming that the character's first name was "Philip" in order to catch
copyright infringement of the book. This incorrect trivium was reused in
Trivial Pursuit, causing Worth to sue the game's publishers. The lawsuit was dismissed by the judge. ==Fictional character biography==
