Catching Fire on BD is like The Dark Knight BD. it is 2.40:1 for majority for it but during the games it switches to 1.78:1 to replicate the IMAX showings

two more for the list but bear with me as i'm not 100% sure on info

The Amazing Spider-Man - IMAX version - 2.40:1 but had scenes that opened up to 1.90:1

Prometheus - IMAX version - opened up to 1.90:1 throughout

never saw these at IMAX though (last film i saw was Superman Returns in 3D) so i'm just going off old info from various places so if anyone has seen these and need to correct me, please do so
