In the upcoming Thor: Ragnarok, Chris Hemsworth's Asgardian hero is getting a bit of a makeover, with some fresh new clothes, new weapons and a new 'do -- he's cut off his long blonde locks -- a change that co-star Tom Hiddleston seems a little jealous of.

ET's Cameron Mathison caught up with the handsome English star at the premiere of his new adventure epic, Kong: Skull Island, in Hollywood on Wednesday, where he said that Hemsworth was "so lucky" that his character got to trim down his 'do.

Hiddleston, who plays the mischievous and often antagonistic Loki, said that he tried get the filmmakers to let his character take a seat in the barber's chair as well, but that the suggestion "wasn't going to fly."

"Yes, Loki still has his long black locks," Hiddleston said.

However, it seems there's more to Thor's new, shorter hairstyle than just an aesthetic choice.

"What I love about it is that there's actually a reason for that haircut," Hiddleston teased. "I'm excited for audiences to find out."

While fans will have to wait untilThor: Ragnarokhits theaters on Nov. 3 to see Hiddleston reunite with his recurring co-star and on-screen brother, audiences are just days away from getting to travel with the actor to the wild and fantastical Skull Island.

At the star-studded premiere, the 36-year-old Golden Globe winner made sure to show his appreciation for his fans by heading out into the crowd to shake hands, sign autographs and snap selfies with his adoring public.

"This is something you never get used to," Hiddleston shared. "We all love making movies and it takes so long to make one, as you know, and it's always such a big night when finally the movie you've made is about to open. This is a different ball game. Kong is an icon and tonight is his night."

For the latest retelling of the classic King Kong tale, the cast and crew headed out to Queensland, Australia, and Hiddleston had nothing but appreciation for getting to work in such beautiful place.

"I actually love being out in the locations because you're having to imagine the creature," he said. "So having the sun and the wind and the heat and the bugs and the swamps was helpful."

That's not to say there weren't a few issues with shooting in Australia. While the deadly creatures Hiddleston and his co-stars face off against in Skull Island are all computer-generated, they couldn't hold a candle to the real-life dangers that call Australia home.

"[It] was hilarious because I think Queensland has the highest concentration of venomous snakes in the world," said Hiddleston, adding that the beautiful locale is also rife with "spiders, plants that could kill you [and] things designed to keep you out."

Kong: Skull Island
-- which also stars Brie Larson, John C. Reilly, John Goodman and Samuel L. Jackson -- tramples its way into theaters on Friday.
