Ellen Burstyn Had To 'Sign In Blood' For Christopher Nolan's 'Interstellar'

If you've taken up the search for juicy plotlines from Christopher Nolan's much-anticipated film "Interstellar," you're probably going to be out of luck. Ellen Burstyn joked Friday on HuffPost Live that cast members had to "sign in blood" to seal their commitment to safeguard details.

"We have all promised we would not say a word, so there's not very much I can say, except to tell you that I have a pretty small part in a very big film," she told host Ricky Camilleri. "Don't expect to see a lot of me."

She did make a point of mentioning that she had "not been cut out," which she learned after seeing Matthew McConaughey at this year's Emmys. The actor also told Burstyn the film is "fantastic and wonderful."

Other than that, the 80-year-old "Exorcist" actress and "Bathing Flo" director couldn't share much more about the film. "It has to do with space. That's safe enough. [And] it's big," she said.

Burstyn did, however, elaborate on her experience working with Nolan.

"He's very smart, very intense," she said. "Very accomplished and knows exactly what he wants."

She concluded by noting that, much to everyone's surprise, the notoriously methodical direction even allowed for "some improvisational moments."
