Who Is Bill Murray Playing In Ant-Man & The Wasp: Quantumania?

Actor and comedian Bill Murray is making his MCU debut in Ant-Man and the Wasp: Quantumania, but it’s unknown which character he will be portraying. While Murray appears in the first trailer very briefly, it could mean he ends up having a significant role during the events of the film. Janet van Dyne’s comments in the first trailer for Ant-Man 3 makes it very clear how dangerous the Quantum Realm really is. Murray’s own statements about his role could also indicate how important his character will be in the movie’s story, and he may not be on the side of the heroes.

Much will be set up by Ant-Man 3’s story, with the Quantum Realm being an important catalyst for what will occur in the third Ant-Man film. Bill Murray’s appearance in the trailer sees him wearing a multicolored outfit and removing a pair of sunglasses from his face. He has a surprised expression on his face, almost as if he is trying to appear welcoming; perhaps he even recognizes who or what he has just seen. The trailer doesn’t reveal anything about the character beyond this, but Murray’s explanation of his role brings up many questions. It also potentially confirms the speculation that he is playing a very obscure Marvel character named Krylar.

At the beginning of 2022, Bill Murray confirmed his appearance in Ant-Man and the Wasp: Quantumania. The comedian also surprisingly revealed in an interview that he would be playing a « bad guy » in the film. While there is a chance that Murray was lying to subvert expectations, it would be a different role for him to add to his typically eccentric career. There are multiple different Ant-Man villains Bill Murray could be playing. While MODOK seemed like a popular choice, seeing Murray appear in human form seemingly debunks this theory. His rumored role as Krylar could be a more reliable option due to his origins in the comics and what it could mean for the MCU.

Krylar is an extremely unknown Marvel character, making a single appearance in The Incredible Hulk #156 back in 1972. The character is not an Ant-Man-related character, but the comic he appears in sees the Hulk shrink down through the Micro-Verse onto the minuscule planet of K’ai. On this planet, Krylar is introduced as a servant scientist to an insane warlord. He reveals a machine that he created which can create a realistic version of an enemy’s greatest fear. Krylar is quickly killed off, but his appearance in Quantumania could be crucial in Ant-Man’s fight against Kang the Conqueror.

While the time-traveling villain may be the MCU’s next Thanos, Kang might not be Ant-Man 3’s main villain. Marvel could be taking a different approach with Bill Murray’s character and decide to show less of him in the trailers so his potential main villain turn could be a bigger surprise. Should he be portraying Krylar, the character’s appearance in the comics could be used to tie into Hulk stories that are adapted into the MCU. If Murray’s appearance in Ant-Man and the Wasp: Quantumania is a one-off like Krylar in the comics, there could still be a significant impact made by his character’s villainous actions.
