The next box set in Big Finish Productions’ audio drama revival of Irwin Allen’s cult classic TV series The Time Tunnel will see Lewis Haworth (Seán Carlsen), MB (Safiyya Ingar), Cole Smith (Jay Reum), and Clare MacGregor (Rachel Handshaw) continue their quest throughout history. And this time, they’ll be joined by a sci-fi legend, as exclusively revealed by the Radio Times. 

Sandra Dickinson is best known for playing Trillian in the 1981 TV series The Hitchhiker’s Guide to the Galaxy. She’s also appeared on TV in The Tomorrow People and Thunderbirds Are Go, and in films including Superman III, Space Truckers, and The Batman, plus Edgar Wright's forthcoming update of The Running Man.  

Dickinson guest stars in The Dimensions of Time’s first episode, Families and Lies – June 28, 1969 as Hazel Hawkins, a widower who is landlady to a young trans woman, Lily Dovecote (Kim Tatum) in Greenwich Village, New York. When the time travellers arrive in Manhattan on the day before the Stonewall uprising, their lives become intertwined with Hazel and Lily’s. 

On making her Big Finish debut with this episode, Dickinson said: “It’s a part to die for! The woman I’m playing has a rich history of being a very good human being, a loving, caring person, and is a tough cookie, so it was really fun to play, and to use the New York accent, which has been in my mind for a long time. 

“The 1960s was an amazing time. It’s so apt at the moment to be talking about the LGBTQ rights movement. It’s really nice to hear how it all started off in New York. And my dear son-in-law, David Tennant, has been standing up for them, bless him! So it’s a great one to have done.”

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.
