Elizabeth Olsen (Scarlet Witch) and Aaron Taylor-Johnson (Quicksilver) we're thrown into their roles early as they gathered to film the Captain America: The Winter Solider post-credit scene, and Olsen was quite nervous.

"It is intimidating going into a production where everyone has their characters fully fleshed out and they know their weaknesses and they have their comedy," Olsen explained to MTV. "Aaron and I don't really have the luxury of time to develop those."

However, writer/director Whedon apparently has no problem collaborating with his team to create another high-quality product.

"I've been doing some fun stuff," Olsen said, according to MTV. "I am unique in this world, and so it's fun to do what I get to do, because it is different. And I think it also is fun for Joss because we're developing and creating something together, and he's getting really excited by it."
