It's been 10 years since the world fell in love with the hilarious antics of Brennan Huff and Dale Doback—two incredibly immature adults trying to cohabitate as step brothersand when Entertainment Tonight caught up with Kathryn Hahn on the red carpet for her new movie Hotel Transylvania 3: Summer Vacation, she was all for a Step Brothers sequel.

"There’s zero plot really in that movie anyway, you could do anything and call it a sequel," the actress quipped. "Anything [at all] and just have that group of people… [and] I would do it in a heartbeat."

In the movie, Hahn plays Alice Huff—wife of Adam Scott's character, Derek Huff, and sister-in-law to Will Ferrell's Brennan—who begins a bizarre romantic affair with John C. Reilly's Doback.

The film featured heavy improv from its cast—something Hahn wasn't used to.

"That kind of broke it open for me as a performer, working with those guys," she recalled. "I mean that was a real anarchic moment for me. I was like, 'You can do this on camera?'"

The 44-year-old actress also admitted that was a turning point in her career.

"I didn’t know you could improvise like that. I didn’t that you could be that lawless. I didn’t know you could throw the script away like that," she explained. "It was the best."
