Troubled Production/Western Animation

Examples of s shown in include:


 * The Simpsons while filming the Radioactive Man movie.
 * The Animaniacs episode "Hearts of Twilight", yet another Apocalypse Now spoof.
 * Metalocalypse: Every single in-universe album during the show's run. The first is done underwater in an attempt to sound as "analog" as possible, deafening the producer. But the biggest example of this trope is the second album: the band procrastinated big time getting it out, causing mass panic. When they finally got to it, Nathan demanded to perform in a suit of armor that made recording difficult, Pickles was starved while everyone else ate, Toki and Murderface produced their own song which, due to how bizarre it was, failed to even make it on the album and to top it all off, Guitarist Skwisgaar Skwigelf was forced by feedback to do his guitar parts skydiving, and thanks to Toki deleting the parts, they did it twice.
 * An episode of What's New, Scooby-Doo? revolved around director Vincent Wong's attempt to make a re-make of a cheesy spy movie Spy Me A River. Besides the lead actor quitting halfway through, no one reading the script, Mystery Inc. being used as stunt doubles, and a Classically-Trained Extra with eyes on the lead role, the production was haunted by the Faceless Phantom.
 * The Wacky Deli episode of Rocko's Modern Life, in addition to being a parodic take on the creation of an animated show, has the titular show being one complete mess from beginning to end.
