Alien actress Sigourney Weaver may be formidable enough to take on four Defenders, but don't expect to see her popping up in the Marvel movie universe right away.

"I'm very happy being in the Marvel with a small 'M,'" Weaver told Movies.com in an interview that discussed both her work with Marvel's Netflix series The Defenders and her forthcoming Avatar sequels with director James Cameron.

Weaver talked about the incredible process of shooting the Avatar sequels all together -- four of them -- while also doing A Monster Calls, an effects-heavy adaptation of a children's favorite.

"Meanwhile, I am doing The Defenders, which is a lot of fun," she said. "It has a wonderful cast, and we're doing it right here in New York, which means a lot to me."

Weaver, who has worked on everything from Working Girl to Ghostbusters, told Movies.com that The Defenders seems different from other superhero projects.

"Basically the four heroes come up against this really nice woman, who I'm playing," she joked, calling Marvel's Netflix shows a love letter to New York City. "To me they're not superheroes; they're people with a gift. It's just a different scale, and I'm really enjoying the scale of it. The apocalyptic thing is a little harder for me to understand."
