NATO list 2022 ATP as $10.58 for 2022, I'd assume 2023 ATP would be something like $10.80, but with the proliferation of PLFs, I think ticket price is drastically different from one film to another, depending on how much PLF and 3D helps the film.
It is hard to imagine any big budget movie with significant PLF has anything lower than $12 ATP these days, Barbie has reportedly $12.65 average ticket price and Oppenheimer at $13.65 for their opening weekends, might go down a bit over time though, Avatar 2 was like $14.5+
