Legendary Pictures has notably worked with both WB and Paramount. Two of Legendary's movies when WB was their primary partner were co-produced by Paramount - Watchmen (marking Paramount's first involvement in a DC theatrical adaptation since the 1940s Superman cartoons, Paramount would be involved in subsequent Watchmen adaptations too) and Interstellar (which Christopher Nolan directed when WB was his primary studio).
Legendary also co-produced the WB-distributed Detective Pikachu, the first live-action film based on Pokemon (notably, Paramount distributes the fourth through seventh anime films in that franchise for Miramax, which acquired those films when it was part of Disney). Although Paramount is now Legendary's primary studio (and they will collaborate on another video game adaptation, Street Fighter, which was originally under Sony even though Street Fighter games have never been exclusive to Sony consoles, the series actually predates the launch of the original PlayStation), since WB is now going to be under the same ownership, any further Pokemon content from Legendary should be housed in that division (as well, WB was the original distributor of the first three anime films in the West). This should also include animated content produced in the West (not the anime stuff produced in Japan), which can include animated adaptations of the Pokemon Mystery Dungeon games and the Poke Park games, plus animated films turning classic cartoon characters under the WB division into Pokemon (like Bugs Bunny into a Buneary).
