'Thor: The Dark World' Spoiler Alert: Viewers Need to Stay for the After-Credit Scenes!
Actor Chris Hemsworth will play a receptionist in Ghostbusters.

Chris Hemsworth has been cast as the receptionist in the all-female reboot of Ghostbusters.

The Hollywood actor, who is best known for playing Thor in Marvel films, is preparing to play the most junior employee in the firehouse in what can only be explained as a gender reversal.

Director Paul Feig announced the Australian-born star's new gig on Twitter, using the original film's famous catchphrase "who you gonna call?"

Feig previously told Entertainment Tonight that although he initially approached Sony about a remake for the 1984 American supernatural comedy film, it was the company's idea to remove Y chromosomes from the equation.

"I love the first one so much I don't want to do anything to ruin the memory of that. So it just felt like, let's just restart it because then we can have new dynamics," he said.

"I want the technology to be even cooler. I want it to be really scary, and I want it to happen in our world today that hasn't gone through it so it's like, 'oh my God what's going on?'"

Although the full cast has yet to be confirmed, Jennifer Lawrence and Emma Stone are reportedly being sought for leading roles alongside Melissa McCarthy, while Feig also says his ideal choice to play the villain would be Game Of Thrones star Peter Dinklage.

The Ghostbusters reboot is planned for a 2016 release.
