Clarke plays Kate, a young woman who previously had dreams of being a big time singer, but after a brush with death due to a frightening illness, she's given up on her pursuit of happiness to live a bitter life as a costumed elf in a Christmas-themed novelty store in London.

Soon, she stumbles upon Tom (Golding), a handsome, kind-hearted stranger who Kate begrudgingly finds herself enamoured with. Tom manages to reignite a spark of happiness in Kate and seemingly helps her rediscover her path.

Directed by Bridesmaids helmer Paul Feig and co-written by Emma Thompson -- who also plays the mother of Clarke's acerbic character -- the first trailer for this smartly written rom-com seems to suggest that there may be some quasi-fantastical elements to the story.

Why does Tom almost always seem to magically appear when Kate is near? Why is Tom always wearing the same tan jacket?  As a Christmas movie, magical realism is par for the course.

There also seems to be some John Green-esque tragedy rippling under the love story. Kate's hospitalization, her obvious depression and sense of alienation all seem to suggest that Last Christmas might bring more heartbreak to the table than we might realize.

Either way, the chemistry between Clarke and Golding feels instant and utterly magnetic, which might end up being the film's strongest feature.

The Crazy Rich Asians star debuted the trailer on The Tonight Show Starring Jimmy Fallon, and teased what fans can expect from the emotional holiday flick.

"It's a beautiful romcom, set in London at the most magical time of the year," Golding shared. "It's one of the most tear-jerking, hilarious movies you'll ever watch."

Last Christmas opens in theaters Nov. 8.
