Highlights from Mark Ruffalo's AMA

Is your friendship with Robert Downey Jr. in real life as good as it is on the screen between your characters?
Better. We have a really good friendship. We've known each other since before Zodiac. And he's kind of like an older brother that I wish I had. He sort of looks out for me, and I remember when the role came up in the movie, I reached out to him, I was nervous about it, I said "I don't know if I can do this" and he said "It's alright buddy, I gotcha."

How much longer do would you like to play Bruce Banner/Hulk?
As long as they'll have me. I did the math, and in 3 more movies I'll be in my 50's, and I don't know if anyone wants to see a gray-haired Hulk. Maybe that's not true...

What makes you Hulk level angry?
People messing up the environment with little care of the people and living things it will effect. Climate Change denial bums me out but that is mostly people who just haven't looked too deeply into the issue or have very little regard for science. Cruelty, and selfishness upset me and greed is a major ugly quality in people.Wars also suck.

Was it difficult not falling in love with Matt Bomer during the filming of The Normal Heart? I mean, the man has a face chiselled by the hands of God...
What more can you say?!

Do you have any particular Eternal Sunshine memories that really stand out to you? That is, if you haven’t had the procedure done.
Dancing on the bed in my underwear with Kirsten Dunst was a hilarious improvised moment. That, and getting beat up by Tom Wilkinson's wife.

If you could rock one Shakespearean role on stage, who would it be?
Oooh wow. Probably Hamlet.

Who's your favorite Pokémon?
Squirtle. For some reason that was the first Pokemon I got on my Gameboy, when I was playing it - they would give you 2 different ones, Charmander or Squirtle, and I started with Squirtle, so I have a warm place in my heart for Squirtle.

What is your favourite Disney movie and what is your favourite thing to do whilst at the Disney parks?
My favorite Disney movie was probably Fantasia. I like Return to Magic Mountain, that's a fun ride.

For 13 Going On 30, did you have to learn the dance to Michael Jackson’s Thriller, or did you already know it?
I had to learn to dance the thriller dance. It took me a long time. MJ was a really good dancer.

What's the best life advice you would give?
Re-define everything that has been taught you. Grasp the unobtainable. Plummet headfirst. Be true to yourself.
