It’s been the biggest secret in theatre: what will the marmalade-loving, hyper-polite Peruvian look like in Paddington the Musical? As the curtain rises, we speak to the new bear’s creator, a veteran of Star Wars and PG Tips ads

Paddington stands within touching distance. His fur flutters as he turns, his neat button nose sniffs the air, and his eyes soften with a smile. For years, design details of the bear for Paddington the Musical, directed by Luke Sheppard, have been kept top secret. Now here he is, in his blue duffel coat and red hat. A quiet theatrical marvel. “What we’re doing,” says producer Sonia Friedman, “has never been done before.”

Standing around 1.2 metres (just under 4ft) tall, the bear is beautifully round, all belly and sloping shoulders. He is not an exact replica of the Paddingtons we’ve seen in illustrations or movies, but something new. His shaggy, caramel fur has a gentle wave, and his white snout is dotted with a brown nose, ideal for sniffing out trouble. Around his neck sits a label, threaded through an old piece of string, asking for someone to look after him.
