CinemaCon movie reveals

Nolan's adaptation of the Greek epic, starring Matt Damon, stunned theater owners with intense footage of a Trojan Horse attack.

Spielberg made a rare appearance to warn that Hollywood must invest in original stories to avoid 'running out of gas.' Other major reveals included a first look at Michael B. Jordan's 'The Thomas Crown Affair' and a hilarious trailer for Mel Brooks' 'Spaceballs' sequel.

The event has reinforced the industry's commitment to the theatrical experience as studios prepare for a competitive summer at the box office.
