From 'Night Court' to 'Everybody's Live With John Mulaney,' Richard Kind is one of Hollywood's most prolific guest stars. Here's what 'terrifies' him.

Richard Kind made a guest appearance on a special musical episode of Night Court, which aired on March 11. The series is a revival of a beloved show that follows a magistrate (Melissa Rauch) who presides over a Manhattan criminal court’s night shift and the kooky characters she regularly encounters.

In the episode, Kind plays Broadway producer Sy Hoffman, who helps a public defender (John Larroquette) adapt his memoir into a musical production. Hoffman is a bit of a slimy and self-serving character, so things don’t go as planned.

In contrast with his character, Kind has built a reputation as an actor who’s willing to make cameos and guest appearances in tons of shows. As he jokes in a cameo on the Netflix series Girls5eva, he’s got “an IMDb page as long as a wizard’s beard.” In the last year alone, he’s appeared on Night Court, Only Murders in the Building, Velma, Evil, Clone High and more in both guest and recurring roles.

Kind spoke with Yahoo Entertainment about Night Court, his legacy and his new gig as the announcer on Everybody’s Live With John Mulaney.

Tell me, what’s going on with Sy Hoffman in this episode of Night Court?

You have to speak a little louder.

What is it? Can you hear me?

I can hear you. It’s me. I’m driving through Palm Springs, and it’s windy outside.

OK, no problem. So tell me, what’s going on with Sy in this episode? What’s he up to?

Oh, he’s a producer!

Yeah! What’s he producing?

You’re asking me like I take this stuff seriously [laughs]! It comes in, and I don’t know what the hell — I did it like five months ago.

OK, I love that —

Talk louder. Talk like you’re talking to a deaf man.

Is your Night Court character, Sy, inspired by anyone?

I did the play The Producers on Broadway. He’s the sitcom version of [Max Bialystock, a down-on-his-luck] producer. But you know, every producer is a producer.

There’s a scene in Night Court when you’re eating a sandwich, and people around are admiring how voraciously you’re doing that. How many times did you have to do that take?

I had to eat that sandwich a lot. Whenever I go to a deli, I never order pastrami or corned beef. It’s bad for me. I try to eat healthy. But this — I’m doing this for my art, so why not? I didn’t spit it out after the take was over — I never do. I just finished it. It was delicious.

OK. I’ll just yell. So, you are famous now for your ability to make cameos or guest appearances in every single show. You have this reputation as someone who’s so generous with your time.

Well, I have to tell you. I try not to do too many of them on TV shows because there’s a stigma for showing up as a guest on so many. You seem like you couldn’t be a regular. But I’m a regular on a lot of TV shows, so I think I have to maintain that. But if they ask me to come in for one time and it’s fun, of course, what the hell! I’ll do it. I like to work. I wish there [wasn’t a] stigma because I like to think of all these things as a repertory company. You go in and get a different playground to play in.

That sounds so fun! I saw you on Broadway not long ago — in All In, which featured John Mulaney. Are you excited to work with him again as his announcer for his new Netflix show, Everybody’s Live?

It delights me. John Mulaney delights me. Doing the show terrifies me.

Oh, no! Why?

Because we’re live! We’re live all over the world! What if I say something stupid? What if I show my true colors? [Mulaney] is so smart, and you want to be as smart as he is. He’s got great guests, and you want to serve the guests. I’m terrified. It’s very scary.

Is there anything else that you haven’t been in that you’d like to do a guest role on?

There’s a whole world of things! But I just like doing the work.

Night Court is streaming on Peacock.
