ANIMAL CHARM: “A lot of people take fashion incredibly seriously,” mused Sadie Frost at the premiere of “Animal Charm,” a new, short film by Ben Charles Edwards at the W Hotel in London on Tuesday night. “It’s good to look at the absurdity of it all — how passionate and desperate people can be — and just have a bit of fun with it.” Peals of laughter erupted from the audience as they watched Frost portray Ann Thrope, an unhinged, fur-obsessed fashion designer decked in Vivienne Westwood clothing. She plays opposite a vegan fashion rival portrayed by the British comic actress Sally Phillips, who wears Zandra Rhodes. And Boy George — amusingly — plays a homophobic policeman. The director — a fashion photographer who has previously worked on films for Giles Deacon — was emphatic that the film did not draw on his own fashion experience. “It was conceived in a diner in Shoreditch whilst drunk, and it was just a bit of fun from start to finish,” he said.
