Paul Walter Hauser is offering a mea culpa for the mean-spirited remarks he made about Vin Diesel in an interview last month.

On Sunday, the Richard Jewell star apologized in a lengthy Instagram post after Hauser implied that the Fast & Furious actor was not known for being on time and approachable.

A few weeks back, I made a random comment about Vin Diesel. It started somewhat humorous, but unraveled into me dogging him out over behavior I had heard about on multiple occasions from multiple sources, Hauser wrote.

The Emmy winner said he had gotten 1 hour of sleep before flying from Los Angeles to Atlanta to do a full day of press for Pixars Inside Out 2.

I was exhausted and, in my fatigued state, I shot my mouth off and made a careless, needlessly mean-spirited, comment. That comment was recorded and then went viral, he wrote. Just here to say that I am sorry for having made that comment.

In a video posted online in late June, Hauser had shut down a CinemaBlend interviewer who compared his voice acting in Inside Out 2 to that of Diesels in the Marvel Cinematic Universe.

Please dont say that, Hauser told the interviewer. Sorry, I love people, but when I hear stories about Hollywood actors who get paid really well and mistreat people, I out them constantly. And its a blast.

Diesel has not publicly addressed Hausers remarks. HuffPost has reached out to reps for Hauser and Diesel for comment.

In his apology, Hauser clarified that hes never met Diesel, adding that hes genuinely sorry for shooting my mouth off and not showing love to Vin.

Hauser also said that it is mean and isnt fair to judge others in the way he did, even if some of those things turned out to be true.

As a self-professed Christian, I need to do a better job of loving people and not trying to right a wrong, or allow my ego to posture itself with some sort of verbal flex, Hauser wrote alongside a quote from the Bible: Make it your ambition to lead a quiet life.

Wrapping up his message, the Cruella actor addressed Diesel directly.

I apologize. Thank you for entertaining so many people and making them happy. Im trying to do the same, Hauser said.
