Gillan has played Nebula in the two Guardians of the Galaxy movies, Avengers: Infinity War and Avengers: Endgame, and Awkwafina will appear in next year’s Shang-Chi and the Legend of the Ten Rings, although it hasn’t been officially announced yet who she’s playing.
Along with their time together on Jumanji: The Next Level (which, like 2017’s Welcome to the Jungle, was a commercial powerhouse with its $800 million worldwide haul), Awkwafina and Karen Gillan also share the Marvel Cinematic Universe in common.
