Michael Cera was looking... very unlike Michael Cera this week.

In fact, the Barbie, Scott Pilgrim vs. the World, and Arrested Development actor apologized as he appeared Wednesday on Late Night With Seth Meyers. When he came out on stage, Meyers said his producer warned him that Cera had gone blond. (See the moment at minute 1:07 into the clip below.)

Meyers said he "didn't quite know what to expect," but he was glad he was prepared for Cera's new look.

"Well, I kind of want to apologize for it a little bit," Cera said. He added, "My hair is in a weird place right now."

The host noted that the transformation is for a Wes Anderson project that was recently shot in Berlin.

The actor doesn't want to cut it just yet, "because then I'll have, like, frosted tips." While he has thought about dying it back to his usual color, ultimately, "that just feels wrong."

Cera will appear alongside an all-star cast that also includes Scarlett Johansson, Tom Hanks, Benicio del Toro, and Benedict Cumberbatch, in the director's upcoming comedy thriller The Phoenician Scheme.

Cera's different hairstyle — especially the brightness — is not unlike the look Vanderpump Rules star Tom Schwartz said he chose because of a "midlife crisis." Fans and the Pump Rules cast endlessly panned the look and Schwartz has since returned to his natural hair color.

Cera's latest project is one in which his hair didn't matter at all. It's Prime Video's animated series Sausage Party: Foodtopia, which came out July 11. It's a sequel to the 2016 comedy movie Sausage Party, in which he played a deformed sausage named Barry.
