"Three Thousand Years of Longing" has just added two huge stars.

George Miller, Deadline reports. Their characters haven't been named yet, but the project is described as a fantasy romance with a genie at the center of it. The plot has largely been kept secret so far.

Elba and Swinton have each starred in a number of high-profile projects. Elba is currently shooting the Fast & Furious spinoff Doctor Strange," among others.

The film's writer-director has an impressive body of work, too. Miller was most recently behind the Oscar-nominated "Mad Max: Fury Road" (and is an out-and-out visionary) so "Three Thousand Years of Longing" is putting together quite a team.

Production is expected to begin in 2019.
