Even the cast of Wet Hot American Summer: First Day of Camp can't believe how much Paul Rudd hasn't aged.
"It's amazing how everyone looks—Paul Rudd looks the same," Bradley Cooper says in the video above.
But seriously, what is his secret?!
In a new behind-the-scenes featurette of the Netflix series, a prequel to the cult-hit flick Wet Hot American Summer, the cast reminisces about their original time together and newbies gush about joining the cast.
"This is our first day, our first day of shooting, and we're all walking around just saying, ‘This is—this is crazy,'" Rudd said.
Wet Hot American Summer came out back in 2001 and the cast gathered again for a new eight-episode series that takes place on the first day of camp. The original movie took place on the last day.
"Everyone looks like they're playing their own parents," Amy Poehler says. Yes, these 40somethings are playing 16 year olds once again.
The original cast includes players such as Poehler, Cooper, Rudd, Christopher Meloni, Elizabeth Banks and Molly Shannon. Newcomers include Chris Pine, Lake Bell, Josh Charles and Kristen Wiig, among others.
"Working on this just feels like when we shot Wet Hot: It's really cold, we're moving really fast and everyone's having sex with each other," Poehler jokes.
Wet Hot American Summer: First Day of Camp hits Netflix on Friday, July 31.
