Emily Blunt talked about the excitement of participating in the movie adaptation of "Into the Woods," the challenges of the green screen, and moving up from singing in the shower to taking actual singing lessons, The Wall Street Journal reported.

Blunt was one among the many stars that took part in Disney's big screen adaptation of James Lapine and Stephen Sondheim's 1987 Tony Award-winning musical "Into the Woods." Playing the Baker's wife, the actress said she was "amazed and moved" at being able to take part in the project.

It was a feat which the actress admitted to be challenging, as she thought the film version might end up being a "watered-down" version of the stage play. However, she was ultimately proud of how the film ended up as dark as the original material.

When talking about the makings of the film, Blunt said she had to rely on her imagination when faced with the green screen.

"We've got moments of special effects when the witch disappears so when you're having to act across a green wall that is tough. That's not as fun," she admitted. "You're having to imagine it and react in a way that doesn't feel as authentic." 

She also talked about how hesitant she was to audition, especially since all the singing she had done was only in her shower. She had to take singing lessons for a few months in order to meet the demands of the film.

"It was a very steep learning curve," she said. 

She talked about the impact of the songs, calling them "an extension of the character," even noting that they were complex and emotionally challenging to perform. She enjoyed her singing lessons though, and called the experience wonderful, according to Den of Geek. 

Blunt admitted though that rigorous and extensive rehearsals and preparations were needed. The official rehearsal took five weeks, but they all needed to prepare for their own parts at their own time. She also complimented Director Rob Marshall for his attention to detail and costume designer Colleen Atwood for their attire.

"I think everyone felt really prepared at the end of five weeks, to just go in there and try to do it justice," she said.
