I thought they only did additional effects in SR? And had no idea about Daredevil.
Why did they go with them? Really if you were in charge of a young company would you like hearing what you have to say? (No offense.)
Chances are, they worked for cheaper (even with a bigger budget than Hulk) as costs went to other things. Either that or Marvel wanted more studios working on the effects for several projects.
You cannot exactly blame Marvel for hiring an Oscar winning studio. It's not like all their resume has is their work like Alvin and the Chipmunks on it.
I personally think their work with animals is amazing. Albeit stylized, therefor I cannot really call it "photo-realistic" then again, if you've seen my posts... I won't call anything in the cinema photo-realistic yet. Not TIH, Not Hulk 03, not Transformers, not Iron Man, not Kong, none of them have really met the "photo-realistic" standard for me.
