Who ya gonna call? Ant-Man, obviously.

Paul Rudd has joined the cast of Jason Reitman’s upcoming Ghostbusters movie, Variety reported Thursday. Details about who he is playing and what role they will have in the plot of the movie are being kept inside the containment unit. But sources say Rudd will play a teacher. (Variety also refers to the new movie as being titled Ghostbusters 2020.)

In addition to the trade’s scoop, the video with Rudd also appeared:

Rudd lending his comedic sensibilities — and Marvel recognition — is a big boost to both the fans and to the movie. The spark he brings to everything from Ant-Man to his Judd Apatow collaborations seem to be a perfect fit for the Ghostbusters’ brand of comedy.

Director Jason Reitman, the son of the original Ghostbusters director Ivan, has worked overtime to keep the plot of his rebootquel under wraps. But according to our Tobin Spirit Guide (read: internet reports), it seems that the Up In the Air filmmaker’s new take will center on a small-town single mom (Carrie Coon) and her son (Stranger Things‘ Finn Wolfhard). Wolfhard’s character may or may not also be a part of a group of ghost-hunting kids. Oh, and that the original cast of the 1984 classic will join in the fun.

We’ll see how this all shakes out when the movie hits theaters July 10, 2020.
