Mariah made her Broadway debut as one of the producers of the stage adaption of Some Like It Hot. Adapted from the 1959 film written and directed by Billy Wilder, Some Like It Hot opened at Broadway's Sam S. Shubert Theatre on December 11, 2022. The musical features a book by The Inheritance Tony winner Matthew López and Amber Ruffin and a score by Hairspray's Marc Shaiman and Scott Wittman, with Shaiman providing music and both contributing lyrics. Tony winner Casey Nicholaw directs and choreographs.
“I first became familiar with this story through the timeless film starring Marilyn Monroe,” Mariah said in a statement. “She's been an important touchstone throughout my life, so much so that I acquired her treasured baby grand white piano at an auction. When [producer] Neil Meron shared this new take on the beloved film, I knew I had to be a part of it. “To see how this show continues to expand on the film's legacy — pushing boundaries, promoting inclusion, celebrating diversity — I'm proud to help bring Some Like It Hot for today's world to new audiences.”
Mariah became a Tony Award nominee in 2023, when Some Like It Hot dominated the nominations for that year's Tony Awards, garnering 13 nods, including Best Musical.
