Guardian's of the Galaxy Vol. 2 star Chris Pratt has apologised to fans after posting a video that asked users to turn the sound up rather than rely on subtitles.

Having been criticised for not being understanding of those who are deaf and hard of hearing – and who therefore depend on subtitles – Chris took to Instagram to say sorry from "the bottom of his heart."

As well as including a lengthy written apology, Chris also uploaded a video of himself apologising in sign language.

After explaining why he asked fans to turn up the volume in his earlier post, Chris conceded: "I realise now doing so was incredibly insensitive to the many folks out there who depend on subtitles.

"More than 38 million Americans live with some sort of hearing disability. So I want to apologise."

This comes shortly after Pratt apologised for making a comment in an interview about there not being enough working class men represented in films.

A lot of apologising this man gets up to.
