The Time Tunnel
"The Time Tunnel" (1966–67, ABC TV), with each episode set in a different historical time period, was an ideal vehicle for Allen's talent for smoothly mixing live action with stock footage from films set in the same period. A change in network management led to the show being cancelled after just one season. Allen cited "The Time Tunnel" as his favorite of all of his television productions and he would attempt to revamp and relaunch the concept numerous times including a filmed pilot in 1976 called "The Time Travelers" and unfilmed concepts that included one called "Time Travel Agency" and another called "The Time Project" that went through several incarnations.
