Walt Disney said on Friday “Guardians of the Galaxy” stormed into the box office with a $11.2 million opening night and could outperform expectations if it keeps drawing viewers with a new leading man, strong reviews and social media buzz. “Guardians,” the newest franchise from the Disney-owned Marvel universe, follows a rogue band of misfits on an intergalactic space adventure. Paul Dergarabedian, senior media analyst at Rentrak said as the Guardians try to save the galaxy from a planet-destroying orb coveted by evil warlords, they may also “save the summer” for a slumping movie industry if the film exceeds expectations.
