As great as Hulk worked in The Avengers, people have wanted a new standalone Hulk movie to follow the only one currently canon in the MCU (The Incredible Hulk). Hulk fans have been hoping for a new outing for the big guy, and if a comment from the original Incredible Hulk is true we may see him again.
Latino Review has found a quote Lou Ferrigno made on a radio interview that claims a new Hulk is on the way:
“Now because he saved the day they’re making another solo Hulk movie after the second Avengers comes out.”
Obviously Latino Review is using this to claim their “Planet Hulk/World War Hulk” rumor is true, although everyone who actually reads comics knows by now that Marvel is building up to The Infinity Gauntlet in Avengers 3 and not World War Hulk. Marvel is expected to unveil Phase 3 at their SDCC panel in June.
