We knew that Ben Affleck and Matt Damon’s Nike film “Air” would open in theaters from Amazon this April, but a new report suggests that the streamer is getting serious about its theatrical ambitions. Variety reported Friday that “Air” will debut a pricey, $7-million Super Bowl ad as part of a build-up to its April 5 theatrical wide release, which Variety now says includes a rollout of roughly 3,000 screens and an exclusive theatrical window comparable to most major studios.
