This exciting continuation of the classic sci-fi series, originally created by Irwin Allen, will debut in February 2025. Originally airing from 1966 to 1967, the iconic series returns with all-new characters set in the present day, offering a thrilling experience for both longtime fans and newcomers alike. 

In 1979, 20 years after it was set up, Project Tic-Toc was shut down by the American authorities. All hope of retrieving scientists Tony Newman and Doug Phillips, lost in the Time Tunnel in 1968, has been abandoned. 

In 2025, four people are brought together by a need to reopen the Arizona base and reactivate the Time Tunnel in secret. From there, they must try to find Doug or Tony because something they have done in the past has changed the present—and not for the better. The world is now under the power of Rakervia. 

Leading the cast are Seán Carlsen (Gallifrey) as British naval officer Captain Lewis Haworth and Safiyya Ingar (The Eleventh Doctor Chronicles) as young hacker MB, alongside Jay Reum as journalist Cole Smith and Rachel Handshaw as marine biologist Clare MacGregor. 

When these four heroes find themselves in a changed world, they must travel through time – using The Time Tunnel, a top-secret installation based in Arizona – to put things right. Over the series, they will visit key moments in history, from the English Civil War to the Stonewall uprising, meet famous historical figures, and work together to restore the world to its proper course. 

Volumes 1 and 2 of Irwin Allen's The Time Tunnel will be released in February and November 2025, respectively. Each volume comprises three exciting adventures through time and is now available for pre-order exclusively here:

• Collector's Edition Triple CD Box Set: £24.99 per volume 
• Digital Download: £19.99 per volume

"Irwin Allen’s The Time Tunnel had the potential to be the most interesting and clever of all his shows, but the story never got a resolution – and that was the launchpad for this new 2025 version,” said Gary Russell, producer and script editor of the new series from Big Finish. “Time travel is also dangerous – as the great writer Ray Bradbury once warned, be careful not to tread on the butterflies…” 

Robert Napton, SVP & Publisher, Legendary Comics, added: “I first started listening to Big Finish's Doctor Who audios at the Gallifrey One convention 30 years ago, so it's been fun to work with Big Finish and our friends at Synthesis to bring another beloved classic series back to the modern era. I am glad producer Gary Russell, and executive producers Jason Haigh-Ellery and Nicholas Briggs, are so passionate about returning to the world of Irwin Allen’s The Time Tunnel.” 

Big Finish listeners can save money by pre-ordering Irwin Allen’s The Time Tunnel Volumes 1 and 2 together in a multi-buy bundle for just £47 (collector’s edition CD and download) or £38 (download only).
