What Could Have Been: A CGI movie of Mighty Mouse, produced jointly by Paramount and Nickelodeon (which would have produced a subsequent TV series) has been in limbo for a few years now.
"Instant Fat," a 1964 cartoon, was storyboarded but never made.
Mighty Mouse: The New Adventures
Executive Meddling: Subverted, then played straight. Until the "crushed flower controversy", the network didn't care what Bakshi and co. produced each week.
Also of note: Season 2's "Bat With A Golden Tongue" was presumed to be a make-good for the "crushed flower" scene in that it entailed Mighty Mouse's efforts to break Bat-Bat of his joke-telling addiction. Bat-Bat's final line to the viewers was "Just say no to canned laughter." For some reason, McDonald's took umbrage and threatened to pull its advertising if the line was not removed. The day before the episode aired, the Bakshi studio replaced the line with a stock scream.
On Facebook, producer Tom Minton revealed that McDonald's objected to the line because it was an all-too-humorous parallel to then-First Lady Nancy Reagan's more serious "Just Say No To Drugs" message.
Hey, It's That Guy!: As mentioned above, the fact that Bakshi was attached to this series attracted several names that would later go on and do great things for American television animation over the next two decades.
Hey, It's That Voice!: Rodger Bumpass, who did narration on several episodes, would go on to voice Squidward on SpongeBob SquarePants. Dana Hill (Scrappy) was an accomplished child actress; Charlie Adler (Bat-Bat) would see success as scores of other characters (such as Buster Bunny on Tiny Toon Adventures), and Michael Pataki (The Cow) would lend his voice to George Liquor.
What Could Have Been: The sudden appearance of a cartoon Merv Griffin was cut out at the last moment from "Night Of The Bat-Bat." It would be used in the unedited edition of the scene in the series finale, "Mighty's Tone Poem."
