Chris joked to The Daily Telegraph earlier this month that being in the fat suit felt like being pregnant.
"It's a silicon sort of prosthetic suit with a zip at the back, and at any moment people would come up and rub my stomach. I know how my wife [Elsa Pataky] feels now when she was pregnant!" Chris told the publication.
"I had weights in my wrist and my ankles to make me move differently, but I enjoyed the transformation and freedom to do whatever I wanted with the character," he added.
Last month, Chris revealed what it felt like saying goodbye to his iconic character Thor after filming for the final instalment of the legendary Avengers franchise wrapped last year.
Speaking to KIIS 106.5's Kyle and Jackie O from Bali, he joked: "It wasn't until weeks after that I realised I was unemployed."
"There was certainly a bittersweet quality to the whole wrapping up of it all - it was 10 years of my life, you know. It's been the most prominent character and film journey I've been on, I've a huge amount of pride [for it].
"It was kind of like high school, saying goodbye to everyone and saying goodbye to my character. I just loved [playing] that character."
The Marvel star said he's held onto some of Thor's trademark props including his beloved hammer, which he plans to auction for charity.
Chris also revealed his wife, Spanish model Elsa Pataky, is sick of his constant shirtless appearances on screen, joking: "She's just like, put your clothes on!"
