An extended version of the first episode, running about 55 minutes rather than the regular 50 minutes. It contains material that was cut from "Rendezvous with Yesterday" and then added to two subsequent episodes: Tony arriving alone outside of the Time Tunnel complex ten years earlier, when he was unknown to the security forces and Doug Phillips (see "End of the World"), and Tony being reunited with Doug in a prehistoric rainforest (see "Chase through Time"). In the pilot film it is Senator Clark, who suggests that Time Tunnel personnel should just go outside the base to save Tony; however, in "End of the World" since Senator Clark is not in the episode, his lines are given to the technician Jerry.
