Episode 8 of Fear Itself sees Cressida joined by one of the world’s most successful magicians, Dynamo, to talk about his fear of not being to perform magic.

Raised on a Bradford council estate, he began performing magic as a defence against bullies and has now performed all over the world. He's also created several hit TV series, including his latest hugely popular Sky series Beyond Belief. Dynamo suffers from a disease of the digestive system called Crohn's, which in 2014 caused him to spend several months in hospital and nearly caused him to give up magic completely - his biggest fear.

Cressida & Dynamo discuss how he faced this, how his time isolated in recovery inspired his magic, and how he puts things into perspective.
