The real stand-ups who helped punch up Bradley Cooper’s comedy-drama ‘Is This Thing On?’

It was abundantly clear to actor-director Bradley Cooper that if “Is This Thing On?,” his comedy-drama set in New York’s stand-up scene, lacked authenticity, the film would fail. With the iconic Comedy Cellar at its heart, he found the key to unlocking that — by casting several of the real-life comedians who regularly take the stage there. Among them were two women at the top of their game right now with sold-out shows and substantial social media followings: Chloe Radcliffe and Jordan Jensen.

“Bradley fell in love with the Comedy Cellar and the relationships that go on there,” Jensen recalls.

“Is This Thing On?” is based on an anecdote from the life of British comedian John Bishop, whose career started when he stumbled into an open-mic night in Manchester, England, while temporarily separated from his wife. In the film, Will Arnett plays a fictionalized version of Bishop, Alex Novak, a finance guy, and the narrative shifts to New York.

“The idea was, ‘If we use people who aren’t comics to play comics, there’s not going to be a juxtaposition between Arnett and this super-tight group of people,’” Jensen says. “His character is this stuffy, bored guy, and he enters into this world of people who have day jobs just like him, but they step into this room, and it’s all dirty humor and busting each other’s balls.”

Radcliffe realized early on that Cooper, who also produced and co-wrote the film, understood the level of commitment required to portray the stand-up world realistically. She saw the first signs of him getting it when he screened 10 minutes of test footage for the comedians at his home, just a few blocks from the Greenwich Village club.

“The second the test footage started, I immediately felt so confident that we are in the right hands,” she recalls. “Any lingering doubt or trepidation was totally washed away immediately, because Bradley just has such clarity of vision and taste. It was clear that he and Will had both embedded themselves deeply in the world of stand-up. Bradley wanted to capture what is real, and he was like, ‘If that means going off script, do it. If that means going to a weird place, do it.’”

Jensen adds, “I don’t think I said one actual line from the script. I would improvise something, and along the way, as I got the point across, it was OK. He might occasionally tell us to say a line, but it was in between 100% moments of improvisation, and he would be rolling camera.

“When I saw the movie, it was really moving. The way he showed it reintroduced me to it and made me be like, ‘Oh yeah, this place is f— magical.’”

Cooper wanted to capture what goes on offstage as well as on, and a significant part of that happened around a particular table at the Olive Tree Cafe, which sits above the underground comedy club. It’s where the acts gather before, after and in between their sets.

“We shot a scene around the comics’ table on the very first day,” Radcliffe says. “About a week or 10 days later, Bradley wanted to reshoot it because he looked at the footage and realized that it looked like a movie. He wanted to make something that looked like the real environment. I admire that so much. Not only is he willing to ask us for our input, but he’s also willing to go back and make new decisions based on new information.”

According to Jensen, in another scene in the cafe, the filmmaker asked whether the comedian’s coats, which PAs had removed from the shot, would be there, and when he was told they would, ordered them to be put back. The level of detail even extended to whether the comics would share fries from a single plate or have their own. It all mattered.

Radcliffe describes Cooper’s reverence for the Comedy Cellar and the comics as an appreciated display of “humility and willing” that extended to both the filmmaker and Arnett, asking for their input on techniques that would improve Novak’s set.

“We wound up chatting about things like where the funny idea is in a punch line, so you might rearrange the sentence so that the most surprising part of it comes at the end. That’s an unnatural way of delivering that sentence,” she reveals. “I would see Will running the set at the Cellar before the shoot, and he is so naturally funny that even if he went off script and started riffing, he instinctively hits punch lines. He has this natural sense of rhythm.”

However, neither the actor nor the director, who also plays Novak’s best friend, Balls, rested on their laurels. To gauge real audiences’ reactions to the material, they ran it multiple times in rooms for months before filming started. It’s something Jensen calls “the ballsiest thing I’ve ever seen a person do.”

“I would be on a show months before the movie was happening,” she says. “They’d be like, ‘Here’s Alex Novak,’ and I was like, ‘Who is that?’ I would see that it was Will Arnett and then I’d be like, ‘F—, he’s bombing. Oh, this is the movie.’”

However, the bombing was intentional, and things would change as the set progressed. She continues, “What I realized is they had written it so that the first chunk in the movie, he doesn’t do so great, the second chunk he does a little better, and the last chunk he does the best, which is how comedy works. I can’t imagine in a million years doing that and not breaking at some point, and being like, ‘Hey, by the way, I’m actually doing this for a movie.’”

While Arnett was on stage, Cooper would stand in the back of the room, taking notes, making changes and doing research. However, Jensen says watching Arnett tank, even on purpose, was “brutal.”

“These were not open mic nights; they were real shows. It was Will Arnett’s reputation, and he was bombing on purpose, but it totally worked out in the long run. He was operating like a real comic up there.”

There were also little things that Arnett did, sometimes by accident, that made his delivery next-level. One example is when he breathes into the microphone.

“It was totally an improvised thing,” Jensen enthuses. “It was this moment of awkwardness that is so authentic that it makes you immediately empathize with him. You’re like, ‘Oh, man, I know that feeling of the air leaving your mouth, hitting the mic, and now everybody has heard that you’ve let out a sigh of grief.’”

Radcliffe, who plays Nina, and Jensen, who plays Jill, are close friends in real life and read for each other’s roles. Aside from being able to take Cooper and Arnett behind the curtain of the comedy scene, their relationship added an extra level of authenticity to the film and to each other’s performances.

“We’ve been really close since pre-pandemic, and she and I have a lot of similar energies,” Radcliffe muses. “We can both be trashy little gremlins. She has a level of aggression that I don’t quite step into, and I think I have a level of exasperation that she doesn’t quite step into. We play off each other really well. She’s so subversive and transgressive, and she’s got such a magnetism in where she is willing to go on stage that I think is unmatched in a lot of other comics working right now.”

Jensen, who is a big fan of Cooper’s work, recalls being starstruck when he first opened the door to his home when the cast came over to read the script for the film. “He opened the door and said, ‘Hi, I’m Bradley.’ I just looked at Chloe over his shoulder, beelined right to her, and snuggled up next to her on the couch, because I was so intimidated,” she said. “It would have still been great if she weren’t there, but having her there was the best. It’s one of those things where when I’m really old, I’ll tell people, and they won’t believe me.”
