The latest live-action reboot of a familiar animated property, classic cartoon "Tom and Jerry," is shoring up its cast, with a TV star joining the ensemble.

Colin Jost -- who's known to "Saturday Night Live" fans as one of the show's longtime co-head writers and the co-host of its Weekend Update segment (and known to "Avengers" fans as Scarlett Johansson's finance) -- has signed on for the big screen version of "Tom and Jerry." Deadline first reported the news, though there are no details yet about what role the comedian will be playing, and whether it will be a live-action character, or animated like the titular cat and mouse.

Jost joins the previously-cast Chloe Grace Moretz and Michael Pena. The flick follows Kayla (Moretz), a new hire at a posh hotel, who enlists the help of Tom the cat to get rid of Jerry the mouse. She eventually ends up banding together with both critters, however, against her bully of a manager, Terrance (Pena).

Tim Story ("Ride Along," "Fantastic Four," "Think Like a Man," "Shaft") is directing and executive producing the feature. No word yet on a potential release date, but "Tom and Jerry" is expected to start shooting sometime later this year.
