Carey Mulligan in fashion at Sundance debut of Mudbound

Carey Mulligan kept cosy in a warm coat and sweater at the premiere of her new film Mudbound at the Sundance Film Festival in Park City, Utah Saturday.

The 31-year-old posed for photographers at the Eccles Center Theatre at the unveiling of the motion picture, which tells the tale of the homecoming of two World War II soldiers, one who’s black, the other white.

The 5ft7 brunette beauty was draped in elegant style to keep her warm as temperatures hit 25 degrees with showers in the area of the cinematic extravaganza.

She wore a camel woolen trench coat with a matching patterned winter turtleneck sweater with gingerbread brown highlights. She rounded out the impeccable get-up with black pants and black shoes, wearing her brown tresses parted and pulled back to some extent.

The Academy Award-nominated actress also posed for special solo and group shots at the premiere, flanked by her collaborators on the motion picture: director Dee Rees, and co-stars Garrett Hedlund, Rob Morgan, Jason Mitchell and Mary J. Blige, the nine-time Grammy-winning songstress who’s sporadically acted in various films and TV shows over the past two decades.

The Drive stunner, who’s been married to musician Marcus Mumford since 2012, plays Laura McAllan in the buzzy film, which is set in the 1940s near the Mississippi Delta. It’s based on a 2008 novel penned by Hillary Jordan.

Carey Mulligan’s campaign to change how we view dementia

The Christmas period is undoubtedly a time many of us look forward to spending with family and friends and that’s no different for me. My beloved grandmother “Nans” turned 91 a couple of days before Christmas and my family and many of Nans’ friends – laden with copious amounts of cake – went down to Wales to see her and celebrate.

Nans and I have always been extremely close and she is the single most influential person in my life aside from my parents. But a lot has changed in our relationship in the last 12 years. Nans was diagnosed with dementia in 2004 and from that moment our lives changed significantly.

But on days like Friday, when we all come together and celebrate her life with those who love her the most, there are still moments of the purest magic.

Dementia is an urgent health crisis that we can no longer ignore. Some 850,000 people in the UK have the condition and more than 47 million people globally live with it.

Its growing prevalence has improved how we, as a society, view dementia. But there is still a long way to go and the stigma of dementia remains rife.

Too many common myths and misconceptions about dementia still exist. Time and again I hear reference to it as just being a natural part of ageing. And, unfortunately, it is often the butt of distasteful jokes.

But dementia is a disease of the brain and it requires understanding, care and support.

The first step in changing people’s understanding of dementia and improving the lives of those who have the condition involves educating people not just on our doorstep, but across the world.

Schemes that set out to change perceptions are doing fantastic work already. The Alzheimer’s Society’s Dementia Friends is a good example. It has 1.7 million people signed up to take action and change the way people think, act and talk about dementia. Through information sessions participants are asked to think about what living with dementia might be like, practically and emotionally, and are encouraged to make changes within their community to make life a bit easier for people living with dementia.

Carey Mulligan joins London protest against bombardment of Aleppo

Hundreds of people including the actor Carey Mulligan have protested in central London to call for the government to end the bloodshed in Syria.

Mulligan joined the demonstration just opposite the gates to Downing Street, where teddy bears were later laid in a poignant message from campaigners about the human cost of the long-running conflict.

Mulligan said Britain could lead the way in efforts to address the plight of children caught up in the bitter war. The crowd included children wearing “Save Aleppo” T-shirts and other people carrying placards urging a “No-bomb zone now”, while some flew Syrian flags.

A small light brown-coloured teddy bear belonging to Mulligan’s young daughter Evelyn was among the pile. “Since having my daughter it just drives home even more how unimaginable it would be for my daughter to be in any of these situations and to have to deal with any of this,” she said. “It just really drives me to speak out and do more if I can.”

The actor told the crowd: “I’m safe in the knowledge that when I put Evie down to bed she is safe. The parents in Aleppo aren’t. They don’t know what the night will bring.”

Mulligan, who is an ambassador for War Child, described the demonstration as an opportunity to “stand up and say that we need to do something real”.

She has previously spoken out to say the inaction in Calais, where many unaccompanied refugee children became stranded in the refugee camp, made her ashamed to be British.

Mulligan said the arrival of young refugees in Croydon this week made her feel “very proud to be British in this regard – we have made a strong stance”.

A letter has been delivered to Number 10 demanding Theresa May take action to help end the violence. It comes after the prime minister insisted on Friday that the EU must keep “all options” open if Russia continued to commit atrocities in the conflict zone.
