fans were thrilled to see series star Brett Goldstein as the newest addition to the Marvel Cinematic Universe when he made his debut in an epic post-credits scene for as none other than the God of Strength himself, Hercules.«When [Marvel] called me and said, 'Oh, we've had this idea, I was like, well, there's something wrong with their space-time continuum,» Goldstein told ET's Cassie DiLaura of the cameo at a Emmys FYC event in Los Angeles on Monday. «I'm in the wrong universe — or the right one, let's face it. Something's happened, I'm being punk'd.»Seeing Goldstein in costume as the Marvel-canon version of the legendary hero made the casting very real though, and Hercules' promise to father Zeus (Russell Crowe) that he would avenge him and make Thor «fall from the sky» already has fans speculating about his involvement in future MCU projects.
