"Ant-Man" star Kathryn Newton said Bill Murray asked her if he could join the franchise.
The 72-year-old actor joins the Marvel Cinematic Universe as a governor in the Quantum Realm.
Newton said Murray called her after they played golf together.
"Ant-Man and the Wasp: Quantumania" sees Paul Rudd's titular hero go up against Kang the Conqueror (Jonathan Majors) in the Quantum Realm, presumably setting the stage for the villain as the new big bad of the Marvel Cinematic Universe.
The film also introduces a few new faces to the MCU, like Kathryn Newton, who stars as Cassie Lang.
