Speaking at the UK premiere of his new film - for which he has also been nominated for an Academy award - he said: "I have a lot of sympathy for it [the boycott] and I completely understand why people are protesting. They have to.

"I’ve been really struggling with it myself because I do a lot with ‘Black Lives Matter’ and I’m really struggling because I would in essence probably really seriously think about joining them."

However, Ruffalo added: "Except I’m in a movie that’s representing a whole other group of disenfranchised people who have no voice and this movie means so much to them.

"So I totally get it and I support them but I have to demur and I have to stand up for the people I have to stand up for."

Ruffalo’s new movie, Spotlight, charts the investigation by journalists at the Boston Globe who uncovered widespread sexual abuse of children by the Catholic Church.
