Jaimie Alexander has revealed that she is in love with her new and improved costume in the Thor sequel.
The 28-year-old actress, who is reprising her role as Sif in Thor: The Dark World, said she has had no problems with the new outfit.
"This one was better! We sort of revamped the costume and it's so much easier," she said.
"I can sit down in it, I had a nap one day - I laid flat and slept on my armour and I woke up, with no backaches or anything."
Jaimie - who stars in The Last Stand with Arnold Schwarzenegger and Johnny Knoxville - has also enjoyed returning to the part in the Marvel superhero movie, which will be directed by Game Of Thrones' Alan Taylor.
"It's been easy to get into that character - she's one of the favourite characters I've played. I just see how young people respond to her and it's so positive that I feel like I'm doing my job," she continued.
The actress also teased that the relationship between the God of Thunder and his childhood friend Sif will be looked at in the sequel.
"In Thor 2, you're going to see a little more of Asgard and we explore the relationship between Thor and Sif. That's something I was so excited about because I find it such an interesting aspect," she said.
Jaimie hinted that fans will see her do more action in the upcoming follow-up, which is due for release in November.
"It's been going great. I had a little setback with a spinal injury in October but I've got back and I've got a couple more fight sequences before I wrap up. I'm really excited, it's been really fun," she added.
