Gemma Arterton proved it would take more than a little London cold to make her cover up her gorgeous dress as she arrived at the premiere of her new film.

She posed with co-star Idris Elba on the red carpet at the 100 Streets premiere at the BFI Southbank in her strapless gown while Idris bundled up in a coat.

The film follows the interconnected stories of several Londoners including an ex rugby star played by Idris and his wife, played by Gemma.

The stories are all lived out within 100 London streets.

Gemma donned a black lace dress with an embellished waist and blue sandals for the premiere.
