Robe Lowe’s addition to the cast of “Super Troopers 2” is not a joke. This is what the actor wanted his fans to know when Deadline broke the news that he has joined the sequel of the 2001 crime comedy film “Super Troopers.”

The 52-year-old actor, who recently starred as Dean Sanderson on the Fox sitcom “The Grinder,” confirmed his casting in the film on social media.

“The secret is out! I've joined the new #SuperTroopers movie!” Lowe wrote on Instagram, alongside a photo of him with other members of the cast.

“This is not a joke. (Although the movie is full of great ones). #Meow #Wig,” he added.

Production for the film began in Boston last week, and according to Deadline, Lowe is playing the role of Guy Le Franc, a former hockey player and the current mayor of a Quebec Canadian border town.

Lowe joins previously announced cast members Jay Chandrasekhar, Paul Soter, Steve Lemme, Erik Stolhanske, Kevin Heffernan, Brian Cox, Marisa Coughlan and Lynda Carter. Chandrasekhar, Heffernan, Lemme, Soter and Erik wrote the film, with Chandrasekhar also directing. Some of Lowe’s co-stars took to Twitter to express how excited they are about Lowe joining the film.

After having filmed some scenes for the big screen project, Lowe also took to Twitter to share what it’s like doing the movie.

“Shooting ‘Super Troopers’ feels like ‘Wayne's World’ or ‘Austin Powers’ did,” Lowe wrote on the microblogging site. “This one could be really special. Insane. Funny. Quotable for days.”

Aside from “Super Troopers 2,” which will be released by Fox Searchlight in North America in 2017, Lowe will also be next seen in Pantelion Film’s “How To Be A Latin Lover”  and Paramount Pictures’ “Monster Trucks.”

On the TV side, Lowe recently joined CBS’ “Code Black,” which will return for Season 2 this fall.
