Spoiler Alert: This interview includes the spoilers of "Poker Season 2" Episode 3, now streaming on Peacock.

FBI agent Luca Clark (Simon Helberg) returns in episode 3 of "The Poker Face", a second season with more murders in season two, more Charlie (Natasha Lyonne) investigations and more guest stars – including stand-up comedian John Mulaney.

The charming murders in Rian Johnson's Anniversary Murder have different Marquis guest stars in each episode. But since Season 1, Helberg has had the opportunity to develop Luca’s trajectory.

"It's exciting to start from driving around the old retired former officials until they crack these important cases for the FBI and get stuck, and it's exciting to start from driving around the old retired former officials," Herberg told Herberg. type. "It's a real dream as an actor because I haven't played a lot of heroic characters yet. It's so cool to play these moments, there's a girl in distress, you pull out your gun and stick your head out of the skylight. That's probably something Luca sees in the movie."

When Beatrix Hasp (Rhea Perlman) tries to find out who the mole is among the crew, this episode brings Helberg back into action with the unexpected help of Charlie. Helberg recalls his first day on the scene – playing the car scene of Beatrix’s murdered husband with Richard Kind.

“It comes in such a big conversation, a lot of, ‘Hello, it’s great to meet you’ and jump into the scene,” Herberg said. “It’s unique because it’s the second season of TV show, but since you have the spinning cast and spinning crew and director, it’s always a bit like the first day of every plot.”

Below, Herberg and Mulaney break the tune of singing Stephen Sondheim, why he thinks Luca will try to imitate "Twin Peaks" Dale Cooper and the "Fever Dream" return to Warner Bros to shoot the Season 3 finale of "Nightclub" recently canceled on NBC.

Tell me your first reaction to reading the script and see that you will play your best friend with John Mulaney, who portrays Danny.

I'm very excited that the "John Mullaney type" mentioned in the script actually turned into John Mullaney. That was a pleasure, because that was how he described it. Even if it ends only As the "John Mulaney type", I would be excited, but I have something real. He could not have been kinder or sweeter. We had to jump in, fight each other, and squeeze each other's cheeks with strange and clumsy battles. We should be our best friends, too. So when you grop out another guy, all of this breaks the ice quickly. Like most people, I've become obsessed with him.

He is a very strange follower, interested in what is happening and everyone around him. His observations distinguish him from others. As far as any form of cliché is concerned, i.e. standing up is awkward or hostile, some clichés, John is far from that.

I know you've already had music training in "Florence Foster Jenkins" and "Annette." Here you and Mulaney can sing some lines from Stephen Sondheim's "We Rolling". Any improvisation?

I am my verbatim. I know John and Natasha (John) were somewhat improvised at their scene when they were arrested. But writing is so keen. The team is very passionate about storytelling - always shocking and shocking in a real way.

We didn’t meet with any music coaches, nor did we work on those beats. I know Sondheim and some musicals, but for some reason I'm not really familiar with "We Roll" actually. I don't know if John is. We didn't really talk much. I think the best thing is to be speechless. I listened to these songs and these phrases, such as repetitive psychopaths.

To a large extent, “Poker Patterns” was inspired by murder mythical performances such as “Columbo” and “Rockford Files.” What movie or show do you think Luca would try to emulate in the way FBI agents?

In these moments, he would say something strange, put on sunglasses, like, he saw the "fugitive". He saw "something to rest". He knew that detectives could have a sense of comfort.

I don't know if I should be embarrassed or it's just a chance, but I didn't see "Twin Peaks" until after the second season. I'm actually watching it, but Kyle Maclachlan's Dale Cooper is totally someone I think Luca may have seen or even tried to imitate. After reading it, I thought, “Wow, that’s the same hairstyle!” There’s a serious and good quality trying to be the best FBI agent you can be. When I opened the script for this episode, I saw something on the third page or in my mind. I'm really scared, but I guess that's the point.

Maybe Luca can imitate Dale Cooper in Season 3. What was it like to shoot that shooting scene, especially as an actor, and many people might be associated with more comedic characters in sitcoms like Big Bang Theory?

It's really technical, and in many ways, I'm doing things that I'm not very good at. Obviously you should have a real binary quality for all of this stuff, and it's not that I have to really spend a lot of time picking up the gun and doing this stunt on the spot. In some cases, mechanically, you only want it to feel it.

This is very fragmented, and this kind of action sequence was filmed. Sometimes you only shoot a moment or the stunt guy falls in the camera, but you are on the ground in the next game. It's like listening to an album in an order and trying to remember where each song is on the playlist because you like "Where are we?" Then you'll see that all of this is put together and maybe 30 seconds on the screen, but there are 50 photos.

You were recently reunited in the season 3 finale of "Nighttime" with Big Bang Theory co-star Melissa Rauch. So what is the shooting experience like?

It's a bit like a fever dream to drive back to Warner Bros. It was really nice to see Melissa and some of the same crew members. I love Melissa very much. It's nice to hint at our exchanges and dynamics about the Big Bang Theory, but still stay away from it. The whole scene is indeed a tip-to-get the audience into the secret past they don't know about her. It's fun to be there to pop up and play different versions of couples.

Finally, since your work in this episode challenges your challenge as an actor, what kind of role do you hope to play after “Poker Faces” in the future?

My goal is to always do something different. I just hoped that there weren't too many beats and too many characters, which was fun. Maybe that's part of it. But when I started the Big Bang Theory, “Hey, maybe we’ll be a pilot and get picked up.” I auditioned like every other job, every other role I’ve ever played, and it happened to last a long time. So, I really long for the opportunity to challenge myself. It does tend to be against the Big Bang just because I did it for so long.
