Ferrigno, who you may remember as the actor who played the Hulk in the 70s television show, will once again be doing some of the voice-work for the MCU Hulk in Age of Ultron.
Ferrigno performed the grunts and roars for Hulk during the first Avengers, but a mix of Ruffalo's voice was used to utter the Hulk's only clear line, "Puny God."
This was confirmed by Ferrigno himself at WonderCon, via Nuke the Fridge. Unfortunately, we still don't know whether or not Hulk will be getting anymore speaking parts when he's not just mild-mannered Banner, but it's probably safe to assume that it will continue to be a joint effort between Ferrigno and Ruffalo.
The Avengers: Age of Ultron opens in theaters May 1, 2015.
What should the Hulk say in the next Avengers?
