"I just try to surround myself with good projects, if I can," Menzel said with a smile, adding that she was also drawn to the film because of its director, Emmy-nominated writer/producer/actress Kay Cannon.
Menzel says playing the role is also "something that sort of encapsulates all the different facets of who I am as a performer."
"It's just exciting," she added with a smile.
Menzel is also looking forward to the release of her long-awaited animated sequel, Frozen 2, which is coming out six years after the original. However, she admitted that finally being done with the project after years of development is a little "bittersweet."
"We really love each other a lot, the entire team. We've been proud of these films and how they resonate with people," Menzel said. "I'm excited for the world to see it."
