Big Finish Blake's 7 range producer Peter Anghelides said: “What a treat to have Steven Pacey back in studio as Tarrant! I wrote his very first Blake's 7 story for Big Finish in 2013, and have long wanted to involve him in The Worlds of Blake's 7.

"The character has such a storied background, and over the years we've speculated on the truth about some of those stories. Our three episodes encompass Tarrant's time at the Federation Academy through to his arrival as a new crew member aboard the Liberator. And so it's also wonderful to welcome back Yasmin Bannerman as Dayna and Alistair Lock as Orac."

Steven Pacey added: "I learned a lot more about Tarrant. It's great to concentrate on Del's psyche, to a greater degree than was allowed or possible in the television series, so I've enjoyed it very much.

"It takes me back to joining this whole series, with Josette Simon who played Dayna at that time, and what an experience that was. And now here we are, doing an audio version with Yasmin playing Dayna. Every actor brings something different to a role, but she brings something very unique and wonderful to it, and it's lovely to have that opportunity."
