Digital

The Avengers was largely shot on digital cameras, which capture the data as information on a hard drive. That made it easier to transport the data here and there, as well as letting the boys in the special effects department do their jobs a little more easily. In a few cases, they still used 35 mm film for some shots, which is done the old-fashioned way.

None of that's unusual for films of this age, when digital cameras were becoming the dominant means of shooting movies. But for a film this big to use digital was a sign that digital filmmaking was here to stay.

Frankly, as long as it makes the film look snazzy, we're all for it.
