Covers Always Lie: The image of Ignatius with a bird on his head which appears on the softcover edition. It must depict the scene late in the book in which Darlene's cockatoo attacks Ignatius because it wants his earring. But the picture doesn't show him in his pirate outfit, which is an intrinsic part of the action of the scene.note There are also two much pickier objections to the picture: The bird is yellow even though, as a rose cockatoo, it should be pink and grey. And it is pecking at Ignatius's right ear even though, when he wears his earring, he wears it on the left. In a way this makes sense: the image does nothing to spoil either the humor or the carefully-constructed confluence of subplots in the scene. But then, why choose that scene for the cover at all?
Development Hell: The Film of the Book, production of which seems to be cursed. Every popular fat comedian since 1980 has been attached to play Ignatius and all of them (John Belushi, John Candy, Divine, Chris Farley) died before the latest attempt of the movie got out of pre-production. So in the early 2000's the producers of the most recent version decided to avoid the whole "fat comedian" thing and got tall and gangly Will Ferrell to play Ignatius (with prospectively some fat makeup) and Lily Tomlin (then later Anne Meara), Mos Def, Paul Rudd and Alan Cumming in supporting roles. Things were going well for this version's eventual production, but then the head of the Louisiana State Film Commission was murdered. Then Hurricane Katrina hit New Orleans. And that seems to be the end of the attempts to make the film for now.
Though recently Nick Offerman starred as Ignatius in a stage version that was widely praised and is set for a run on Broadway in 2016.
