Created by producer Irwin Allen ( Lost in Space, The Poseidon Adventure ), this vintage show from the early 1960s follows two young scientists, Tony Newman ( James Darren ) and Doug Phillips ( Robert Colbert ), as they head up the ambitious government project Tic Toc. During a demonstration of their prototype for a time travel portal, Tony impulsively tries it out, landing on the Titanic just before it sinks. Naturally, Doug dives in after him, and they get stuck in an endless adventure as they travel through time, hoping that eventually their colleagues will figure out how to retrieve them.
