Chris Hemsworth's Ghostbuster laughs

Chris Hemsworth kept "cracking up" while filming 'Ghostbusters'.

The 32-year-old actor - who plays receptionist Kevin in the upcoming reboot - couldn't keep a straight face because his co-stars Melissa McCarthy, Kristen Wiig and Kate McKinnon were so funny in their improvisations.

He said: "There's some nice role reversal there and I'm such a fan of those women.

"During shooting I spent more time cracking up and trying to keep a straight face, and there'll be more outtakes from that than anything else I've ever made.

"This is highly improvised work - they just kept the camera rolling for hours."

Chris was initially opposed to the idea of a remake of the 80s classic, but when he heard about the gender role-reversal, he was desperate to be involved.

He admitted: "When I heard they were doing a male 'Ghostbusters' I thought, 'No they can't do that, it's sacrilegious, it can't be remade.'

"Then when I heard it was being done with a different spin and a female cast, I knew it was going to be something unique. So when I was offered it, I immediately thought, 'Awesome'."

The Australian hunk can next be seen in 'Snow White and the Huntsman' prequel 'Huntsman: Winter's War' and was pleased he got an opportunity to return to the saga.

He told Gay Times magazine: "I loved the script the first time round and it came right off the back of 'Thor'.

"There were things I liked that we achieved and things I thought we could have done better in the next one.

"So having another opportunity means you really get to explore things that you may have missed.

"This time round, there's a lot more humour and a larger sense of fun and adventure to it. The first film definitely had a darker palette and style."
