Amy Poehler reveals she shared a dressing room with Meryl Streep during ‘SNL50’

“There were so many people that people had to share dressing rooms,” Poehler told O’Brien. “So, I was sharing my dressing room with Meryl Streep. Just like a fan, I was taking a picture of the door that said my name and Meryl Streep.”

She went on to describe watching the legendary actress prepare for her “SNL” debut.

“She was getting ready for her sketch and really rehearsing it and I remember thinking, ‘I have never rehearsed as hard as Meryl Streep has in this one moment,'” Poehler added.

Streep made her first-ever “SNL” appearance during the anniversary special’s “Close Encounter” sketch joining Kate McKinnon, Woody Harrelson, and Pedro Pascal at the Pentagon to discuss their alien encounters. The recurring skit follows McKinnon’s character, Colleen Rafferty, as she vividly recounts bizarre and often suggestive alien abductions — while manspreading and smoking a cigarette.

For the anniversary special, Streep played Colleen Rafferty Sr., the equally unfiltered mother who also had raunchy run-ins with extraterrestrials. Known for making co-stars break character, McKinnon may have met her match in Streep, who stole the show.

Poehler also found herself sitting next to Jack Nicholson in the audience during the star-studded evening. The Oscar-winning actor introduced his “Anger Management” co-star Adam Sandler’s performance in the show.

“In the seats, which was a night of all famous alumni and people, I sat down and turned to my left and it was Jack Nicholson,” Poehler said. “I was like, ‘Of course. My old friend, my dear friend Jack Nicholson.'”
