Timothy added a pop of colour to his quirky ensemble by wrapping a colourful scarf around his neck.

The Harry Potter star completed his look by wearing a black shirt tucked into a pair of black trousers and smart shoes.

His co-star looked the picture of 70s chic as she wore a tan, fur-lined jacket over a white T-shirt with a graphic print.

She completed her look by wearing a pair of flared light-wash jeans, and accessorised with gold hoop earrings.
