Who ya gonna call? Paul Rudd.
The actor has announced he's joining the cast of the next "Ghostbusters" movie.
In a video posted to social media on Thursday, the "Ant-Man" star said he can't wait to join the cast this fall.
Ivan Reitman directed the first two "Ghostbusters" films, and his son Jason Reitman is helming the new movie, which is set for a 2020 release.
The last "Ghostbusters" movie, which was released in 2016, featured an all-female ghost-busting crew.
