Big Finish has announced a second boxset of full-cast audios in Irwin Allen’s The Time Tunnel: The Dimensions of Time

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.

What stories are covered in this new boxset?

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). Please note: the collector’s edition CD box set is strictly limited to 1,000 copies and will not be repressed.
