What Happens Next? - 10 MORE Planned Seasons Of Cancelled TV Shows
3. Quantum Leap
In Quantum Leap, Dr. Sam Beckett is a physicist who travels through time to rectify history's mistakes. Each time he performs a quantum leap, he inhabits the body of a person from that time period. For five years, viewers wondered if the doctor would ever return to his own time and body. The show ended with the most anti-climatic phrase possible, "Dr. Sam Becket never returned home." Just to add insult to injury, they didn't even spell his name right.
According to the lead actor, Scott Bakula, an ending was filmed which showed Beckett's friend, Al, and his wife, Beth, becoming leapers to bring Beckett home. For over 20 years, fans of the show didn't know if there was any truth to this ending or if it was mere speculation. But in 2019, a video validating this ending was uploaded online. It is unknown how the uploader obtained this footage.
Other ideas that were thrown around for the final season were for Beckett to "leap" into Tom Selleck's character from Magnum PI, a baby, and a cartoon character. (It's probably best these stories never saw the light of day.)
