As reported in Playbill.com's most recent "Smash" Report episode recap, "composer-lyricist Marc Shaiman and lyricist Scott Wittman, who provide original songs for the series (for Marilyn, chiefly), have (with creator Theresa Rebeck and consulting producer Michael Mayer) come up with an ambitious, knockout sequence called 'Let's Be Bad,' a musical scene in which a compromised Monroe shows up on the set of 'Some Like It Hot' to sing and dance a Jazz Age song as film crew, husband Arthur Miller, techies and chorus kids surround her."
Hilty also spoke with Playbill.com about the surreal nature of filming the musical within a musical moment. "I was playing Ivy Lynn, Ivy Lynn was playing Marilyn and Marilyn was playing Sugar in 'Some Like It Hot' and she shows up wasted and is having a hard time doing the number," Hilty recalls. "But they're filming it on stage, so there's a fake camera crew, and a fake director on stage, and then there's the real camera crew that's out in the audience and above us swirling around us capturing it all. It was a lot to think about."
