To people collecting Marvel movies: Does anyone know if the iTunes copy of Guardians of the Galaxy has an aspect ratio that switches to the taller IMAX version during the selected scenes that were filmed that way? It should be easy to tell as soon as the opening title sequence.
I've been recently disappointed that 'The Dark Knight Rises' and 'Interstellar' do not do this (and yet, 'The Dark Knight' does), so for me, bluray is the best way to go for those two movies. But Guardians is from a different studio so I don't know what to expect.
Other recent Marvel films might have had some scenes shot in IMAX, too(?), but Guardians of the Galaxy is the only one I know for sure.
