Why Leslie Mann was flustered by Adam Demos

During an interview on SiriusXM’s Smith Sisters Live on Tuesday (August 11), Leslie discussed meeting Adam for the first time.

“You know what I was just thinking, and I forgot, we’ve never talked about this, but the first day I met [Adam], we were rehearsing with Scott and John, and I watched Sex/Life during COVID alone. Yeah. I was quarantining alone and yeah, I had that,” Leslie said.

Isla cut in and said, “Where are you going with this? Where are you going?” Adam added, “I’m just going to leave the room.”

Leslie continued, “When I was told it was going to meet Adam, I was like, ‘Oh, oh, oh, okay, that’s good.’ And then I was like, you know, kind of nervous to meet him because I had this, you know, private time with him. Oh god. And I remember he walked in, he had his like sunglasses on his head and I was trying to be cool and I was not cool. Like I was really like sweating and I remember looking at him in the eye and trying to, you know, just be cool and my eyes went, like they just shifted. Did you see that?”

Adam said he didn’t notice that. He said, “No. But I’m also coming into your movie, in your world. So I’m like, ‘I hope I can like show up,’ and so we’re both thinking two things like, ‘Oh boy.'”

Leslie said, “You seemed so much more calm and cool and collected than me. Anyway, but that happened. Yeah, I’m glad I got that off my chest.”

The cast attended an L.A. special screening

Leslie, Isla, and Anna were joined by Adam while attending a screening at the London Hotel in Los Angeles on Tuesday night.
