Mojo's adjusted numbers aren't comparable between pre-3D and post-3D openings.
IMAX and PLF surpluses only factor into the first 1-3 weeks of a run for a big film. 3D shares tend to be negligible outside of blockbusters, and decrease over the course of a run. As such, big films have higher average ticket prices than mojo suggests.
Older films also lacked all of these surplus charges. Therefore, adjusted openings on Mojo for all blockbuster films prior to 3D are underestimated.
Spider-Man 1 would have opened around $200M by today's standards if we make the (incorrect) assumption that its venue count would have been the same as 2002, and if would have largely missed a Thursday/Midnight preview.
A 2017 film with the same momentum as Spider-Man 1 would have probably been in the $215-230M range.
