Christian Bale said he had no idea what to do with the green screen on the set of Marvel s Thor: Love and Thunder.

In a recent interview with GQ Magazine , the 48-year-old actor, who starred as the skin-tight black speedo-wearing supervillain Gorr the God Butcher in the recent Thor sequel, opened up about the monotonous filming experience.

Thats the first time Ive done that, he said, referring to green-screen acting. I mean, the definition of it is monotony. Youve got good people. Youve got other actors who are far more experienced at it than me. Can you differentiate one day from the next? No. Absolutely not. You have no idea what to do.

Love and Thunder, the fourth film in the Thor franchise, hit the big screen in June and follows Thor (Chris Hemsworth) on a quest to find inner peace while clashing against Bales god-slaying villain.

Although Bale previously got a taste of the super-powered realm from suiting up as Batman in the Dark Knight trilogy before ditching DC Comics for the Marvel Cinematic Universe, he admitted that he fumbled through the filming process.

I couldnt even differentiate one stage from the next, he recalled. They kept saying, Youre on Stage Three. Well, its like, Which one is that? The blue one. Theyre like, Yeah. But youre on Stage Seven. Which one is that? The blue one. I was like, Uh, where?
