Details are scarce, but the love story is said to involve a genie.

Idris Elba and Tilda Swinton have come aboard to star in Three Thousand Years of Longing (aka Djinn), the new movie project from Mad Max: Fury Road filmmaker George Miller.

The duo are attached, although no official deals have been made, as the project is not yet set up and no financing has been secured. That could change very quickly in the coming days or weeks as Miller begins to shop the project to studios and financiers timed to next week's American Film Market.
