Megan Hilty would "fall on the floor" if she got to meet Meryl Streep.

The 42-year-old actress is gearing up to take on the role of narcissistic performer Madeline Ashton in the musical adaptation of 1992 film 'Death Becomes Her' and admitted that she would struggle to cope if the film's original actress got in touch with her ahead of the premiere.

Megan told People: "I don't know her and I can't imagine that she has any time to reach out to me. But I'm sure that they're aware that this is happening. I would fall to the floor[if Meryl reched out]. I don't know if I'd be able to take it."

Megan - who is known for her role as Glinda in the Broadway production of 'Wicked' and later starred alongside Katharine Mcphee in the NBC musical drama series 'Smash' as a wannabe actress competing for the part of Marilyn Monroe - is due to open in April and spoke of how the role is "good enough" that she and her husband Brian Gallagher are relocating to Chicago for the show's pre-Broadway tryout with their nine-year-old daughter Viola.

She said: "We did a workshop this summer, and it's really excellent. It's good enough to uproot my entire family and move them across the country for a year.

"Madeline Ashton is such a delightful part, and they've written such incredible songs for me to sing.

"What I love is that in general, not just for my character, but for everything, they made such smart changes in adapting it to the stage.

"They didn't just pluck it from the movie and set it on stage. It really is crafted for the theater, and there's such wonderful Easter eggs in it for people who love the film.

"It's just enough that it gives everybody what they want and remember from the film, but it also breathes a whole new, different kind of life into the story."
