The 48-year-old actress co-stars with Chris in the upcoming 'Thor: Ragnarok' and joked that the handsome actor is extremely unattractive.

When asked about Chris, 33, she quipped: "That ugly, un-fit individual?"

However, Cate went on to add to Entertainment Tonight: "He's one of the great men. He really is the mensch and he's an extraordinary actor. And he has the patience of a saint. I mean, because we were filming 'Thor' in Greenland and it was pretty bloody hot, and what he has to wear and the hours...So, I mean, he's a real leader."

Cate has four children with her husband Andrew Upton and revealed that her daughter Edith was particularly impressed with her work on 'Thor: Ragnarok'.

She said: "It's really exciting for kids to be on the set and also it's such a family the Marvel Universe.

"It was Edith's first experience of being on set with me, so she thinks that's what I do all the time. She thinks acting is manifesting weapons out of your hands and killing people."

Cate's character Hela, a goddess of death, is the first real female villain in the Marvel universe and Cate is happy that Marvel is "catching up".

She said: "Wow! It's taken this long to catch up! But you know, Marvel is catching up at a rapid, rapid rate. You've got Captain Marvel coming out with Brie [Larson] and I mean, all these incredible women who are in Black Panther...and Scarlett [Johansson] of course."
