Big Finish Productions’ revival of Irwin Allen’s 1966-67 cult classic TV series The Time Tunnel, under licence from Legendary Entertainment, returns in 2026 with a second volume of three episodes. 

In the previous box set, February’s The Nightmare Begins, Captain Lewis Haworth (Seán Carlsen), young hacker MB (Safiyya Ingar), dark web operative Cole Smith (Jay Reum), and marine biologist Clare MacGregor (Rachel Handshaw) found themselves in a changed world, controlled by the sinister Rakervia. 

In a secret military base in Arizona, they reactivated the Time Tunnel and set out across history, on a mission to track down the lost scientists Tony Newman and Doug Phillips, and restore the world as it should be. 

That quest continues in the three new episodes that make up the second box set, The Dimensions of Time. This time around, the tunnel takes our heroes to New York at the time of the Stonewall uprising, France during the Hundred Years War, and the doomed Titanic. 

Irwin Allen’s The Time Tunnel: The Dimensions of Time is available to pre-order now for just £19.99 (download to own) or £24.99 (download to own + collector’s edition 3-disc CD) exclusively here. Please note: the collector’s edition CD box set is strictly limited to 1,000 copies and will not be repressed.   

The three brand-new time-twisting tales are: 

Families and Lies – June 28, 1969 by Mark B Oliver 

Cole arrives, alone, in Greenwich Village, Manhattan on Saturday, 28th June 1969, the day before the Stonewall uprising. With Lewis and MB nowhere to be found, he forges new friendships, but they have their own troubles. Inside the Project Tic-Toc Control Room, Clare must persuade Elenya that reuniting her friends is in all their interests. 

Divine Intervention – April, 1429 by Lisa McMullin 

MB and Cole find themselves in 15th Century France, towards the end of the Hundred Years War. It’s France versus England but MB and Cole will be lining up on the side of France – alongside the Maid of Orleans herself – Joan of Arc. Is she a witch, a heretic or a feminist revolutionary? 

Rendezvous with Tomorrow – April 15th, 1912 by Gary Hopkins 

MB and Cole follow in the footsteps of Doctors Newman and Phillips aboard the doomed passenger ship Titanic in the year 1912. It seems that, after all, history can be re-written. Clara MacGregor, meanwhile, discovers that the past can be read in different ways. Is it possible that the journey’s end is in sight? 

Producer, director and script editor Gary Russell said: “The Time Tunnel is one of those great Sixties science-fiction shows that ended too soon and without resolution. Ever since I was six years old, I used to think, what happened to poor Doug and Tony? To finally have the opportunity to restart Project Tic-Toc's computer spools, flashing lights and boot up the Tunnel again – and along the way maybe finally get an answer to Doug and Tony’s fate – was simply too good an opportunity to pass up on. 

“We've had so much support and encouragement too from Legendary and Synthesis – who look after the Irwin Allen properties with so much love and respect – and for that I’m really grateful. They gave us the chance to bring The Time Tunnel into the twenty-first century with a bang.”
