Collateral Beauty trailer: Will Smith talks to Love, Death, and Time

It didn't take long for Will Smith to sign on to this December's Collateral Beauty. "It was one of those where you get a screenplay and you are in by page 10. You just go, 'Okay, I'm making this one,'" Smith told EW last month. "It's a really beautiful story and one of those movies that makes the holiday beautiful."

At the time Smith wasn't really able to tell EW too much of the plot beyond the basics: his character, Howard, had suffered a terrible tragedy (now we know: the loss of his daughter) and he has become unmoored in his life. But, Smith cautioned, there is a twist he could not reveal. "It's delicately framed in a way that's going to be tough to promote — you just can't say anything," he laughed.

Now with this first trailer — which you can watch above — we can understand maybe a little bit more about what Smith was talking about. Helen Mirren, Keira Knightley, and Jacob Latimore play Death, Love, and Time, respectively — all seemingly summoned by Howard, who has been writing and mailing grief-stricken letters to the big three. Or are they? Smith described the movie (directed by David Frankel and also starring Edward Norton and Kate Winslet) as It's a Wonderful Life meets The Wizard of Oz — and if that makes sense to you, congratulations — so we may have to wait till Dec. 16 when Collateral Beauty arrives in theaters to know the full story.
