Stevyn Colgan: Mr Green and Mr Gray Cannot Visit us Today

Given the bewildering variety of life on Earth – all stemming from one self-replicating molecule – can we really predict what life on other worlds is like? Maybe not.

Stevyn Colgan, now a QI elf and a writer for Radio 4’s The Museum of Curiosity, has been involved with aliens for three decades. He’s held Jabba the Hutt’s face, helped sculpt creatures for Bruce Willis to shoot at and had a script accepted for Doctor Who in the 1980s.

His new book ‘Why did the policeman cross the road?’ is now available to pre-order via Unbound.co.uk
