Never underestimate Marvel Studios and their marketing team as tracking numbers for Ant-Man have improved significantly in just over a week.

Initial tracking had Ant-Man pegged for a soft $55 to $60 million debut in North America, but now The Hollywood Reporter believes it could open as high as $65 million.

That's significant because no Marvel film has opened below $65 million since 2008's The Incredible Hulk, which grossed $55.4 million in its domestic debut. A $65 million debut for Ant-Man would be on par with Marvel's 2011 films Captain America: The First Avenger ($65M) and Thor ($65.7M).

Of course Ant-Man could overperform because it is considered one of the more family-friendly Marvel films, but don't expect it to even sniff Guardians of the Galaxy $94.3 million stateside debut.

Armed with the astonishing ability to shrink in scale but increase in strength, con-man Scott Lang must embrace his inner-hero and help his mentor, Dr. Hank Pym, protect the secret behind his spectacular Ant-Man suit from a new generation of towering threats. Against seemingly insurmountable obstacles, Pym and Lang must plan and pull off a heist that will save the world.

Marvel's Ant-Man hits theaters July 17, 2015.
