10 Actors Who Appeared In Star Trek AND The MCU
These actors have flitted between the Final Frontier and the Avengers but how many did you know?

With the epic(ly long) announcement that Rebecca Romijn, Sir Patrick Stewart, Chris Hemsworth, and Kelsey Grammer are set to reprise their Marvel roles in Avengers: Doomsday, audience interest in the Star Trek/MCU crossovers is peaking. We've known for years that the Star Trek Universe contains superheroes, even if they don't all shed on the furniture.
Films like Doctor Strange And The Multiverse Of Madness and The Marvels brought some of the Trek actors from Fox's Marvel films into the main MCU, nestling them all under the smiling behemoth that is Mickey. Other Trek actors have made appearances in Marvel projects, like Eric Bana in Ang Lee's Hulk, Donna Murphy in Sam Raimi's Spider-Man 2, Doug Jones in Fantastic Four: Rise Of The Silver Surfer, and Shohreh Aghdashloo in Fox's X-Men: The Last Stand.
Star Trek: Starfleet Academy will bring She-Hulk's Tatiana Maslany into the franchise, as well as The Amazing Spider-Man 2's Paul Giamatti. Yet more Star Trek performers have appeared in the dozens of additional Marvel properties - they're getting quite hard to miss. Michelle Hurd appeared in both Daredevil and Jessica Jones, and Alive Eve appeared in Iron Fist.
For this article, we are focusing on the main MCU film series that began with Iron Man in 2008. There are so many crossovers, don't surprised if you see a sequel list in the not-too-distant-future.
10. Chris Hemsworth

Before he was lifting hammers and bemoaning 'the worst brother,' one of Chris Hemsworth's first film parts had a rather important role in Star Trek: he died so that James T. Kirk could live. When one considers the legacy that character has left behind, there's very little argument that George Kirk did the right thing aboard the USS Kelvin.
Hemsworth, fresh-faced and not long removed from the rolling waves of Summer Bay, served as first officer under Captain Robau (played by another MCU guest star, Faran Tahir) when Nero and the Narada arrived to ruin everyone's day. The ship was quickly crippled, the captain was dead, and Kirk the senior was in command. Acting to save his wife (played by Jennifer Morrison, who voiced the Wasp in The Super Hero Squad Show) and son, he piloted the Kelvin on a collision course with Nero's ship.
Plans for a fourth Kelvin-era film have been in limbo for years, though Hemsworth was approached to reprise the role in what would presumably be a time-travel story. He has kept busy in the interim, appearing as Thor in more than ten appearances to date, several of which with Star Trek Beyond's Idris Elba.
He is set to reprise the role in Avengers: Doomsday along with Tom Hiddleston, returning as Loki.
