Cobie Smulders on Playing Maria Hill in The Avengers

Smulders, who was Whedon’s first choice for his shelved Wonder Woman feature, said that they “start in April, which is like… tomorrow. I literally leave here and I go to Albuquerque, New Mexico, to shoot some scenes in a catsuit.”

She added that she has “tried on portions of the catsuit [and] I’ve seen conceptual drawings of what they want it to be. It’s fascinating to me. I feel like wardrobe becomes very creative on these types of movies because they literally spend weeks designing just the pants or the emblem. It’s such an all-consuming process, so I’m excited to see how it all turns out.”

Smulders will be joined by the all-star cast of Robert Downey Jr., Chris Evans, Chris Hemsworth, Jeremy Renner, Clark Gregg, Scarlett Johansson, Samuel L. Jackson and Mark Ruffalo in New Mexico. Walt Disney Pictures will release Marvel Studios’ The Avengers on May 4, 2012.
