Also, I guess there's a cross-promotion of sorts:

A special promotion ties the Mortal Kombat II(2026) film to WWE, featuring a Fandango early access fan event in IMAX that includes a ticket to WWE WrestleMania 42 in theaters. WWE wrestlers Xavier Woods and Kofi Kingston are partnering with the film for a meet-and-greet event. The film, a sequel to the 2021 Mortal Kombat, is scheduled for 2026.
