21 Laps Developing Film Based on Larry Niven’s ‘Inconstant Moon’

21 Laps, the company behind Stranger Things and Arrival, is hard at work on another scifi project – an adaptation of Larry Niven’s short stoty Inconstant Moon. Inconstant Moon, which won the 1972 Hugo for best short story, focuses on a couple dealing with their relationship issues during an apocalyptic event.

Y’know, fun stuff.

Daniel Casey is writing the script, and James Ponsoldt is currently directing. 21 Laps’s Shawn Levy and Dan Cohen are producing, along with Ponsoldt under his 1978 Pictures banner. Personally, I think this could be pretty cool (assuming it gets out of development), as more intimate stories set in extraordinary circumstances can sometimes be some of the best.

Hopefully we get to find out.
