The upcoming eighth series of the hit comedy will be its last, and the 52-year-old actor - who plays Lieutenant Terry Jeffords on the sitcom - admitted the episodes will be "intense" but "fun."
"It's going to be intense, it's going to be lovely, it's gonna be fun," he told Entertainment Tonight. "We've been in tears, because we finished it. It's (been) eight seasons of joy. You're gonna laugh your head off."
He teased "a lot of unexpected wonderful things" from the final run.
"(It's) literally the perfect, perfect way to end it," he added.
Meanwhile, Terry previously revealed four new episodes had been scrapped following protests against police brutality across the U.S. in 2020.
"Our showrunner Dan Goor, they had like four episodes all ready to go - they just threw them in the trash. They're like, 'We've got to start over,' " he said.
p> "Right now, we don't know which direction we're going to go in, but we do know that we've had a lot of sombre talks, we've had a lot of very, very deep conversations, and through this we hope to bring something that could really, really truly be groundbreaking this year."
"We have an opportunity here and we plan to use it in the best, best way possible."
The TV show is fronted by Andy Samberg. It received multiple nominations at the Primetime Emmys and won Golden Globes including Best Actor in Television Series Musical or Comedy for Samberg.
