Owen Wilson jokes about getting an 'ominous text' from Marvel after accidentally revealing he grew a mustache for his 'Loki' role: 'Strike 1'

• Owen Wilson revealed his "Loki" character had a mustache.
• "I got an ominous text saying 'Strike one,'" he told Esquire.
• The actor joked that he thinks it came from Marvel head Kevin Feige but it "was never confirmed."

Owen Wilson may have learned firsthand just how serious Marvel Studios is about not leaking spoilers.

"I can tell you it's no joke," the "Loki" star revealed in a recent interview with Esquire.

"Even when I let it slip that I'm wearing a mustache [as] Agent Mobius I got an ominous text saying 'Strike one,'" Wilson said. "I don't know who that was from. We looked into it and we think it might have been [Marvel Studios head] Kevin Feige using a burner phone or something but that was never confirmed."

Whether or not Wilson was joking and if he received a text at all is hard to tell, but Marvel projects have always tried to keep any possible spoilers locked down. That can range from the typical stuff, like not giving cast and crew the full script, to more intense tactics, like covering surprise-cameo guest stars with blankets and umbrellas on their way to set so paparazzi can't take a picture of them.

But sometimes it goes further, as "WandaVision" star Kat Dennings once shared on "The Ellen DeGeneres Show."

"You know, [Marvel] sends us a thing of what we can't say, instead of what we can say [while doing press]," she said.

So who knows? Wilson may be completely serious when he says he got a text that seemed to warn him to keep quiet about his facial hair and other Marvel secrets.
