Rebecca Rubin Film and Media Reporter There’s been a battle brewing between two of Hollywood’s blockbuster talents. In one corner, Tom Cruise is gearing to take a victory lap from the behemoth success of “Top Gun: Maverick” with a sequel to his other big action franchise, “Mission: Impossible – Dead Reckoning Part One.” It’s expected to be one of the biggest movies of the summer when it opens on July 12. In the other corner, Christopher Nolan, one of the few directors so famous that his name alone can draw crowds, is readying to release his highly anticipated “Oppenheimer.” The big-budget drama about the creation of the atomic bomb launches just a week later on July 21.
