Carey Mulligan and Marcus Mumford brave snow at Sundance

They are madly in love and raise their two young children together.

So of course Carey Mulligan, 32, promoted her movie Wildfire at the Sundance Film Festival with the support of Marcus Mumford, 30, in Park City, Utah, on Saturday.

The married lovers, who tied the knot five years ago, looked closer than ever as they braved the snow to grab a coffee on route.

Hollywood actress Carey wrapped up in style in a warm coat embellished with eye-catching buttons, which looked like huge golden coins.

The mother-of-two wore her golden locks in a soft beachy waves and she enhanced her natural beauty with a minimal dusting of make-up.

Marcus bundled up in a coat to keep the chill at bay and toted a suitcase as the pair took some time away from parental duties.

Carey slips takes on the part of housewife and mother Jeanette who embarks on a passionate love affair with an older man, as witnessed by her 16-year-old (Joe Brinson) in her latest movie Wildfire.

Meanwhile, her character’s husband Jerry (Jake Gyllenhaal) is away from home fighting an uncontrolled forest fire.

The leading lady admitted she was initially nervous about working with her good friends Paul Dano and Zoe Kazan on the set of her latest movie.

But the mother-of-two revealed it paid off in the end as it was a ‘really amazing’ experience to be able to work with close pals.

‘There was a kind of triple threat of fear involved in working with people I’ve known as friends for a decade,’ she said at the festival.
