Rachel McAdams Wears Form-Fitting Sequin Dress to 'Send Help' London Premiere, Hugs It Out with Dylan O'Brien

Rachel McAdams looks stunning on the red carpet for the Send Help premiere in the UK!

The Oscar-nominated actress shared a cute hug on the red carpet with co-star Dylan O’Brien on Thursday night (January 29) at Odeon Luxe Leicester Square in London, England.

Rachel wowed in a sequined form-fitting gown while Dylan went casual in a suit and white shirt.

Also stepping out were director Sam Raimi with girlfriend Anne-Katrin Hallaschka, plus his daughter Emma Raimi, who appears in the film.

Here’s the official synopsis for Send Help: “Linda Liddle (McAdams) and Bradley Preston (O’Brien) are two colleagues who find themselves stranded on a deserted island after they are the only survivors of a plane crash. They must overcome past grievances and work together to survive, but ultimately, it is an unsettling and darkly humorous battle of wills and wits to make it out alive.”

Send Help hits theaters on January 30. Watch the trailer here!
