So I was just like, Mm, I dunno if I dig this, dig that, right?

And I had a passion for this show, but Im not the producer of the show, right?

But when he left it was just like, Okay, so now I gotta deal with this.

The actor said that tension with Schneider came to a head in a verbal altercation.

I remember me and Dan had a big argument on set.

He was like, Lets go over here to this room right here, in this closet.

Mitchell said that he opted to remove himself from the altercation.

I had a decision to make, you know what I mean?

I was just like, okay, either we going to fight or either Im going to leave.

And so thats what I did.

I left the situation.

The comedian said that he was so upset that he asked his parents for advice.

So I called my parents, I called my dad, he said.

My dad was like, Have you felt disrespected in any key in of way?

Do I need to I fly out there?'

Being the man that I am now, I shouldve let them fly out there.

But I just was kinda like, No, no, no, I got it.

A rep for Schneider did not immediately respond to EW’s request for comment.

Schneider initiallyapologized for his behaviorin a 19-minute response video following the debut ofQuiet on Set.

“Watching over the past two nights was very difficult,” the producer said.

I feel so guilty saying that, he said.

All those things started happening after our tenure, because, I guess, no one would even dare.

It wasnt that kind of environment.

There was no dictatorship about it all.
