Thor: Ragnarok spoilers given away by TV host, Chris Hemsworth unimpressed

While Marvel Studios has been watertight on releasing Thor: Ragnarok, others have been less so.

First, there was Hulk actor Mark Ruffalo, who accidentally live-streamed the first 20 minutes of the world premiere on Instagram.

Now, an Australian TV host has revealed a key plot-point from the upcoming blockbuster, leading to a rather embarrassed Chris Hemsworth trying to cover up the gaff.

During an interview with The Project, a reporter asked Hemsworth and Ruffalo about Cate Blanchett’s character Hela, referring to the Goddess of Death as Thor’s sister on multiple occasions.

Unbeknownst to the reporter, knowledge of Hela’s relationship to Thor has not been revealed to the general public — in the comics, Hela is Loki’s daughter and Thor’s niece.

“You can’t say it’s his sister, you can’t give that away,” Hemsworth said, Ruffalo adding: “ixnay on the istersay.” Watch the interview below, the spoiler moment happening around the 6:20 mark.
