The high street clothing store has released its Christmas advert, directed by Wes Anderson, as part of its Come Together campaign, and it's pretty spectacular.
Starring Hollywood actor Adrian Brody as train conductor Ralph, the three minute, 42 second ad is one of the longest and most lavish we've seen so far.
Wes Anderson, who directed blockbuster film The Grand Budapest Hotel, has used his big screen talents to help us feel even more festive this Christmas.
The advert opens with Adrian Brody in the conductor's carriage on the H&M Lines Winter Express. He tells the passengers that due to bad weather and a train delay, their journey will be delayed by 11 and a half hours, and will only reach their destination at 3:17am.
As he's talking, the camera looks into each carriage giving us a view of the passengers as they learn they won't be home for Christmas.
However, determined not to let the train delay ruin the holidays, Ralph sets out on a mission to create a Christmas brunch. Along with porter Fritz, Ralph works hard to find enough decorations to have a special day. He even manages to get a Christmas tree passed through the window.
19 minutes later a little boy looks a bit nervous as he makes his way down to the train carriage to find the Christmas brunch.
But as he walks in he finds a magical winter wonderland, full of decorations, paper snowflakes and the rest of the guests in Santa hats.
The little boy joins the rest of the passengers, while conductor Ralph helps him put the star on top of the tree. As the guests circle round the tree, the heart-warming message 'Come Together' appears on screen and really reminds us of the kindness of strangers.
Talking about the lovely message behind the short film, Adrian said: 'This story may resonate more than ever at a time in the world where we could all do with giving a stranger a hug.
Pernilla Wohlfarhrt, Head of Design and Creative Director at H&M, added: 'The winter train ride, under Wes Anderson's direction, is the perfect setting for H&M's Christmas collection full of relaxed, wearable elegance.
'It's about mixing the informal with a sense of occasion, capturing the holiday mood for both dressing up and getting cosy with loved ones.'
