“Frozen II” star Evan Rachel Wood has been making surprise appearances in the cast of interactive-theater sensation “Sleep No More.”

Sources told Page Six that Wood has played the Nurse in two recent performances at the McKittrick Hotel. A source said, “The part requires interaction with the audience, and everyone was so excited to spot her. After the show, she joined the cast onstage in the late-night ‘McKittrick Follies’ at the hotel’s Manderley Bar where she sang [Beatles song] ‘All You Need Is Love.’ ”

Spike Lee, Shia LaBeouf and “The Crown” star Vanessa Kirby have recently been spotted in the audience of “Sleep No More.” Sacha Baron Cohen and Rose McGowan were at the same venue to check out Susanne Bartsch’s wild “Bartschland Follies” show. Wood — who also stars in the HBO series “Westworld” — slammed the new movie musical “Cats” as a disappointed fan ­recently, posting online: “I am actually speechless. [It’s] maybe the worst thing I have ever seen. Ever.”
