This is my thought. I have to believe there’s a solid inverse relationship of interest. But everyone is interested in one of them. Parents/kids or men/women seem like sensible cohorts for Oppenheimer/Barbie.

Would be interesting to see the data and if showtimes overlap. Or if it’s truly back to back.

I think you have a too narrow view of people’s interests.

I would describe the overlap as “people into films that are with a relatively high likelihood interesting”. Given who is directing and who is involved with both of those films that’s a relatively safe bet.

Fast & Furious in a double feature with Trolls. That’s what I would describe as double feature with little overlap. Both films have probably relatively distinct demographics that like them and the films are unlikely to be in any way interesting.

I'd also speculate that animated childrens movies are not likely to overlap with much at all in terms of double feature worthiness.
