Jiminy Cricket Appearances
The character in the original novel, 1883's The Adventures of Pinocchio, is simply called the Talking Cricket. He shows up for the first time in the fourth chapter, speaks to Pinocchio once, and is promptly killed by a mallet, only to show up later as a ghost. The fact that Disney took this idea and spun out the dapper little gent that is Jiminy Cricket, and then managed to use him as their go-to host for all sorts of specials and other media is just one more example of their expertise as a marketing juggernaut.
the 1972 Italian animated movie The Adventures of Pinocchio veers much closer to the book. The Talking Cricket is still anthromorphized like his predecessor, but his personality is much closer to the novel and he definitely gets killed by a mallet. He's voiced by Lauro Gazzolo, and Don Messick did the english dub.
the 1996 live action movie the Adventures of Pinocchio is probably best remembered by kids from that era as the one with the puppet voiced by Jonathan Taylor Thomas. Here the cricket is named Pepe, and is voiced by David Doyle. This is in the early years of CG animation in feature films, and people were still working out how to make character look not-terrifying.
Roberto Benigni's 2002 movie Pinocchio is a really odd duck. This was right after he earned massive international success (and the oscar) for Life is Beautiful, and he followed it up with this surreal take on a children's story that, frankly, kinda creeps everyone out. Here the Talking Cricket is played by curmudgeony Italian Actor Peppe Barra, with an english voice dub by John Cleese.
The ABC series Once Upon A Time was about fairy tale creatures all having their own town in the real world, and because it was created by ABC it had access to the entire Disney lexicon, which meant it quickly became Disney: the live-action series. Jiminy Cricket as he appeared here was 100% the Disney version, with his real-world counterpart played by Raphael Sbarge.
the 2002 Italian-British miniseries Pinocchio is best known for casting perennial favorite Bob Hoskins as Geppetto, but it also stands out for it's casting of Luciana Littizzetto as the Talking Cricket, with the character skewing closer to the Disney version in that she's around more and considerably more helpful.
Most recently, there's the 2019 Italian feature film Pinocchio, which is again based much more heavily on the original novel. Here the talking cricket is played, in some very cool make-up, by Davide Marotta.
But of course, the OG version is still the one of the first adaptations of the source material, and also the most commonly recognized take on the character. The original 1940 animated Disney film has so completely co-opted the public awareness of this story, most people probably aren't even aware that the Talking Cricket was ever called anything other than Jiminy. He's become such a major touchpoint in pop culture that it barely occured to me that Sarah casually calling Jareth's conscience his "Jiminy Cricket" even qualified as mentioning a character at all.
