10 Awesome Pitches To Extend TV Shows (That Sadly Never Happened)

2. The Zapp & Kif Show

When Futurama finished up its run in 2013, co-creator David X. Cohen took part in a Reddit AMA where he was asked which characters he'd most want to make a spin-off show for.

Cohen replied that a Star Trek-esque adventure starring Zapp Branigan and Kif was constantly considered, to the point that a backdoor pilot of sorts was almost made on several occasions.

As for why they never even got the one-off episode made? Cohen said, "We were nervous that people would get confused and angry, and throw things at the TV."

This one really stings because it's such a brilliant and organic idea, allowing the Futurama universe to exist without Fry, Leela and co, while training the focus on two beloved supporting characters and poking fun at a classic sci-fi series at the same time.
