From Norman Lear's spin-off empire to the NCIS franchise that spawned over 1,000 episodes, these are the backdoor pilots that were way too obvious.

🎬 What's a backdoor pilot?
A backdoor pilot is an episode of an existing TV series designed to launch a spin-off. The regular cast takes a backseat while new characters are introduced — and if the network likes what they see, those characters get their own show.
