"James Franco is the star and I play his mother," Burton told Playbill.com. "It's a very small part but a very interesting part [and was an] incredible experience."

Burton said she loves stretching her muscles in multiple media: stage, film, TV. "I do, I love going back and forth. I shot '127 Hours' up until three days before I started work [on The Grand Manner]. It's really amazing to go from being on a film set in Moab, Utah, and then four days later to be at Lincoln Center. I feel very blessed that I get to do all these different kinds of things and I love it. Once the play ends, I hope for some film stuff and TV stuff in the future. I have a few things…but nothing's materialized yet."

The new film, "127 Hours," is based on rock climber Aron Ralston's memoir, "Between a Rock and a Hard Place," the true story about the young man being trapped between rocks for 127 hours and resorting to cutting his own arm off.

Burton said, "I can only imagine [the film 's] gonna be pretty amazing. I play his mom, and his actual mother, Donna Ralston, has become a friend of mine. She's coming to see the show this weekend! But we spent some incredible time [filming it]. James Franco plays Aron, and Treat Williams and I play his parents. We were in Utah — well, Treat lives there, in Park City — we were there, off and on, for about six weeks shooting. Amazing experience, and Danny Boyle, to work with Danny Boyle is like a dream come true for me."

Also in the can for Burton: the film "Remember Me," starring Robert Pattinson and Pierce Brosnan. She plays Brosnan's executive assistant.
