Trueman spent 20 years at Granada TV and while there he wrote and presented the TV series Cinema and conceived, produced, wrote and presented House for the Future.

However, he was best known for his work writing for the animation company Cosgrove Hall Films, particularly Chorlton and the Wheelies, some of the scripts for Count Duckula, and the original Danger Mouse episodes, which were voiced by Sir David Jason.

Cosgrove Hall Films Archive paid tribute to Trueman on Instagram, saying: “We’re very sad to hear of the passing of Brian Trueman.

“For many years Brian worked for Cosgrove Hall Films as writer, voice actor and narrator.

“Brian’s writing and humour had the unique ability to appeal to both adults and children, which contributed to the success of Cosgrove Hall series such as Danger Mouse, The Wind in the Willows, Jamie and the Magic Torch.
