"I think it's going to be awesome," the Oscar-winner told ET Canada on the red carpet at the Toronto International Film Fest premiere of Manchester by the Sea, which he produced.
Damon starred as pickpocket Linus Caldwell alongside Brad Pitt and George Clooney in Ocean's Eleven, Twelve and Thirteen.
Ocean's Eight, which is set in the same universe as Damon's Las Vegas heist trilogy, is set to star Anne Hathaway, Sandra Bullock, Helena Bonham Carter, Cate Blanchett, Sarah Paulson, Rihanna, Mindy Kaling and rapper Awkwafina.
Damon had nothing but praise for the impressive cast, sharing, "They're going to kick ass."
The film, which is set to begin shooting in October, reportedly follows a group of female thieves who a plan a multi-million dollar jewelry heist during the Met Gala.
As for Manchester by the Sea, Damon couldn't help but heap praise on the indie drama, written and directed by Kenneth Lonergan and starring Casey Affleck, Kyle Chandler and Michelle Williams.
"It's so beautifully written. It's one of best screenplays I've ever seen," Damon shared. "I was initially supposed to direct [the film], and I read it, and I was just slobbering in tears. I just called Kenny immediately and said, 'Kenny, you have to direct this. There's no other way that this can be done.'"
"Probably, as a producer, the smartest thing I did was getting out of the way," Damon added.
Manchester by the Sea, which premiered at the Sundance Film Festival in January, hits theaters Nov. 18.
