@neal weird related fact I learned recently - Quantum Leap was developed from the original plan for the Battlestar Galactica 1980 revival which would have involved Apollo and Starbuck going back in time each week to solve problems after finding Earth.
@neal yeah, I just stumbled across that the other day while reading about the original series cancellation dramas. Found it interesting that the concept that was rejected went on to be so successful in its own right.
