Magnum P.I. crossover
Sam made some rather surprising leaps, once even becoming Lee Harvey Oswald, the man who assassinated President John F. Kennedy in November 1963.
Sam once almost leapt into fictional character Thomas Magnum, who was played by Tom Selleck.
Creator Donald P. Bellisario had pitched the idea to the NBC, and despite ‘Magnum P.I.’ having been off-air by that point, the crossover idea was seriously considered, with Tom Selleck himself being approached to reprise the role.
Sadly, the episode was never made.
