Michelle Dockery with Julianne Moore at the photocall for their new movie, Non-Stop

Michelle Dockery has cemented her A-list status once and for all, as she posed with Hollywood legend Julianne Moore at a photocall to promote their new movie, Non-Stop.

Wearing a beautiful floral shirt dress with contrasting white collar by Erdem and her favourite Rupert Sanderson heels, Michelle looked every inch the movie star. Julianne Moore, who stars opposite the Downton Abbey star in their upcoming blockbuster, looked equally gorgeous in a black dress with lace overlay, and strappy Louboutins sandals.

Also starring Liam Neeson, the film takes place on an international flight from New to London. During the flight, an air marshal receives threatening text messages that state the passengers lives will be at risk, unless $150 million into a secret bank account. Michelle Dockery plays flight attendant Nancy in the action flick – needless to say, it sounds like a far cry from Lady Mary's sedentary in Downton Abbey.

12 Years A Slave actress, and our current red carpet queen, Lupita Nyong'o, also stars in the film.

That makes three of our favourite leading ladies in one film – we can't wait.
