Next year’s Ant-Man movie, Ant-Man and the Wasp: Quantumania, will feature William Jackson Harper in a secretive role, it seems. Variety reports that the Good Place star will appear in the movie, noting that his part in the film “remains a closely guarded secret.”

Harper’s character, whoever it may be, did not ostensibly appear in the new Quantumania trailer. Marvel declined to comment when approached by Variety about Harper’s reported casting.

In any event, Harper would join the Quantumania cast that includes returning actors Paul Rudd, Evangeline Lilly, Michelle Pfeiffer, and Michael Douglas. Scott Land’s daughter Cassie Lang (Kathryn Newton) will have a bigger role in the sequel, which will see the family team up to fight Kang the Conqueror (Jonathan Majors) in the quantum realm.

Quantumania arrives in theaters on February 17, 2023. For more, check out GameSpot’s breakdown of every easter egg and clue you may have missed in the recent Quantumania trailer.

The next MCU movie is Black Panther: Wakanda Forever, which releases on November 11. After that comes the Guardians of the Galaxy Holiday Special on November 25 featuring Kevin Bacon’s introduction to the MCU.
