The Touching Reason Sally Field Starred in 'The Amazing Spider-Man'

Though she didn't like the role, she did it anyway for dying friend.

But despite the limitations the role presented for the Oscar winner, she did the movie anyway and did it for a very real reason.

"It's not my kind of movie," she admitted to Howard Stern Tuesday on his radio show. But the 69-year-old actress signed on to the production anyway because the movie was producer Laura Ziskin's last film, as she was dying of cancer at the time.

"We knew it would be her last film," Field added. "She was my first producing partner. She was spectacular." Ziskin succumbed to the disease in 2011.

Field went on to say that Aunt May just wasn't "three-dimensional," though the actress' turn as Spidey's mother figure was still one of the standout performances in the film.

"You work it as much as you can," she said of the limited role.

"It's not the Aunt May movie," Stern added.
