Mark Ruffalo coached 'Fantastic Four: First Steps' star Ebon Moss-Bachrach through computer generated performance "insecurity"

Marvel newcomer Ebon Moss-Bachrach received some advice on bringing to life an entirely computer-generated character from longtime franchise cast member Mark Ruffalo, who has played Bruce Banner/The Hulk since 2012's The Avengers. 

"I got a really nice, very long, thorough text from Mark Ruffalo because my character is performance-capture, and I was a little anxious about that, it's something I've never done before," the actor shared during a press conference for Fantastic Four: First Steps. "Mark immediately, I don't know if somehow he got wind of my insecurity about it, and he was really generous and sort of went through the whole thing with me." 

Set against the vibrant backdrop of a 1960s-inspired,
retro-futuristic world, Marvel Studios’ “The Fantastic Four: First Steps” introduces Marvel’s First Family—Reed Richards/Mister Fantastic, Sue Storm/Invisible Woman, Johnny Storm/Human Torch, and Ben Grimm/The Thing as they face their most daunting challenge yet. Forced to balance their roles as heroes with the strength of their family bond, they must defend Earth from a ravenous space god called Galactus and his enigmatic Herald, Silver Surfer. And if Galactus’ plan to devour the entire planet and everyone on it weren’t bad enough, it suddenly gets very personal. 

Moss-Bachrach, best known for his performance on FX's The Bear, is taking on the role of Ben Grimm/The Thing. The rest of the cast includes Pedro Pascal, Vanessa Kirby, Joseph Quinn, Ralph Ineson, and Julia Garner.
