IMAX - Wikipedia
I saw Speed Racer today at an IMAX theatre. My last experience at what I thought was an IMAX theatre turned out to be an OMNIMAX theatre which is very different than current standard IMAX. So I was disappointed to say the least. Not in the film itself, which not only holds up upon repeat viewings, but becomes even better. (John Goodman's performance is very good by the way.) If you have access to a digitally projected film theatre, there is no difference in clarity between that and IMAX. Not to my eyes. Yes, the IMAX screen is taller, but that is not relevant to a conventionally shot movie which is typically wider than it is tall. OMNIMAX is the greatest film experience but for some reason still deemed too expensive to film and there are not nearly enough screens to support such a film if it was to be made. I am hopeful that digital cameras could be cheaply made to support the OMNIMAX format and that digital projection of such "films" would be far cheaper and encourage the building of OMNIMAX screens.
