NBC's "Today" show has canceled an appearance with "Big Eyes" star Amy Adams over her refusal to discuss the recent Sony Pictures cyberattack.

"As a news program, the 'Today' show doesn't allow guests to dictate restrictions on interviews," an NBC News spokesperson said in a statement. "In this case, after hours of discussion we felt uncomfortable with the demands being made and we determined the best course of action for all parties involved was to cancel the interview."

Adams, who plays artist Margaret Keane in the film, opening Thursday, was scheduled to be a guest on the show on Monday.

Some of the hacked Sony Pictures documents had indicated that Adams, 40, and Jennifer Lawrence were paid less for their integral starring roles in "American Hustle" than their male fellow stars, Christian Bale and Bradley Cooper. Adams, Lawrence and Bale all received Academy Award nominations for the movie.

The Weinstein Company, producer of "Big Eyes," said in a statement, "We firmly stand behind Amy Adams. We've been lucky enough to have had her talents grace several of our films. We are certain her fellow actors and directors would all agree, she is nothing but the consummate professional both on and off set. Amy decided to speak up for herself and express her disappointment that 'Today' would feel the need to ask her a question she did not feel comfortable [with], and rather than respect her opinion or continue the discussion, the reaction was to pull her appearance from the show."

Efforts to contact Adams' publicist were unsuccessful.
