Moviegoers who went out to see Thor: Ragnarok at the Vista Theatre on Nov. 3 in Los Angeles got more than they bargained for.

Chris Hemsworth and Tessa Thompson, who plays the Asgardian Valkyrie in the film, were there to greet — or rather, surprise — the fans.

Thor, Valkyrie Shocks The Crowd

Thor: Ragnarok director Taika Waititi took the stage at the screening to introduce the Marvel movie, but from the look of things, he had an ulterior motive.

"I also have some friends I'd like to bring out," he told the audience, which already got some of them excited. "Guys, can you please come and join us?"

As everyone can imagine, the crowd went wild when Hemsworth and Thompson stepped into view and toward the stage, getting one heck of a stroke of luck.

Hemsworth Thanks The Fans

As a show of gratitude, Hemsworth uploaded a clip of the event on his Instagram page and thanked everyone who watched Thor: Ragnarok.

Of course, the fans returned the favor and expressed their appreciation for the gesture.

"I️ saw it on Saturday and loved it! I️ was supposed to wait for my friend to watch it on the 11th! The Valkyrie tho!!!" c_ware_im_goin wrote.

"OMG Yup, I would have died. #awesome surprise for your fans!" authorericarstinson said.

It's also worth mentioning that Marvel Studios tweeted about it too.

Thor: Ragnarok has been quite a success, earning a positive score of 73 at Metacritic and a 93 percent rating at Rotten Tomatoes. Fans particularly liked how the movie featured the first female lead villain in a Marvel movie Hela, who is played by Cate Blanchett.

That's not everything the film's got going on, though. The epic action scenes and cast all make it the success that it is today, including Hulk and Loki, whom Mark Ruffalo and Tom Hiddleston play respectively.
