Will Arnett, known for his comedic roles in television shows like “Arrested Development” and “BoJack Horseman,” is stepping into a more personal and vulnerable space with his latest film, “Is This Thing On?” The comedy-drama, directed by Bradley Cooper, explores the complexities of a marriage coming to an end and a midlife search for purpose, with Arnett taking on the challenge of trying his hand at stand-up comedy. The film, released December 19, 2025, has garnered positive reviews, particularly for Arnett’s performance and Cooper’s direction.
“Is This Thing On?” isn’t a traditional biopic, but rather “loosely based” on the life of English comedian John Bishop, who received a story credit for his contributions. IMDb details that the film follows Alex, played by Arnett, as he navigates the awkward aftermath of a split from his wife, Tess (Laura Dern), while attempting to redefine himself through the unpredictable world of stand-up. The film also stars Bradley Cooper, Andra Day, Amy Sedaris, Sean Hayes, Christine Ebersole and Ciarán Hinds.
A Comedy of Remarriage and Reinvention
Described as a “comedy of remarriage,” according to Wikipedia, “Is This Thing On?” delves into the nuances of a couple learning to live separately while co-parenting their two sons, Felix and Jude, and maintaining their established friendships. The narrative explores the challenges of identity and the possibility of finding new meaning after a significant life change. Arnett’s character, Alex, finds himself struggling financially after the separation, leading him to try open mic nights at the Comedy Cellar as a way to both earn money and explore a new creative outlet.
The film premiered at the 2025 New York Film Festival on October 10, 2025, before its wider release. Its exploration of mature themes and relatable relationship dynamics has resonated with critics and audiences alike. Rotten Tomatoes reports a Tomatometer score of 86% based on 198 reviews, and a Popcornmeter score of 83% based on over 500 verified ratings as of February 28, 2026. Rotten Tomatoes highlights the film as a “terrific relationship study” and an “ideal platform for Will Arnett’s dramatic chops.”
Bradley Cooper’s Directorial Vision
“Is This Thing On?” marks Bradley Cooper’s third directorial effort, following “A Star Is Born” (2018) and “Maestro” (2023). Critics have praised Cooper’s direction, noting a shift towards a more understated and intimate style. Alejandro Alemán of El Universal called the film Cooper’s “best film to date.” Rotten Tomatoes compiles several reviews noting this, and Roger Salvans of Fotogramas observed that the film feels “almost modest,” prioritizing silences over spectacle.
Cooper co-wrote the screenplay with Will Arnett and Mark Chappell, bringing a collaborative energy to the project. The production companies involved include Lea Pictures and Archery Pictures, with Searchlight Pictures distributing the film. The film’s cinematography is by Matthew Libatique, and the editing is by Charlie Greene, with a musical score composed by James Newberry. The film runs for 121 minutes.
Critical Reception and Performances
The performances of Will Arnett and Laura Dern have been singled out for particular praise. Dwight Brown of DwightBrownInk.com described the film as having “enough romance, comedy and drama to keep adult audiences amused and beguiled.” Rotten Tomatoes showcases this review. However, not all reviews were entirely positive. Sandra Hall of the Sydney Morning Herald noted a lack of “spark” between Dern and Arnett, and suggested that while the cast seemed to enjoy making the film, that enjoyment didn’t fully translate to the audience experience.
The film’s exploration of midlife crises and the challenges of modern relationships has struck a chord with many viewers. The narrative’s authenticity and relatable characters contribute to its appeal. The film’s box office performance, reaching $12 million, demonstrates a solid, if not blockbuster, level of success.
Arnett’s Transition to Stand-Up
The film’s premise – a successful actor attempting stand-up comedy – draws parallels to Arnett’s own career trajectory. While Arnett is primarily known for his comedic acting roles, “Is This Thing On?” allows him to showcase a different side of his talent, exploring vulnerability and self-doubt. The film’s exploration of the stand-up world offers a glimpse into the challenges and rewards of performing live comedy, and the courage it takes to place oneself on the line.
The film’s narrative, inspired by John Bishop’s experiences, highlights the often-unseen struggles of comedians as they hone their craft and navigate the competitive world of comedy clubs. The film doesn’t shy away from the awkwardness and failures that are often part of the learning process, adding a layer of realism to the story.
Looking Ahead
“Is This Thing On?” represents a significant step for both Will Arnett and Bradley Cooper. For Arnett, it’s an opportunity to demonstrate his range as an actor and explore more complex and emotionally resonant roles. For Cooper, it’s a continuation of his growth as a filmmaker, showcasing his ability to tell intimate and character-driven stories. The film’s success suggests that audiences are receptive to thoughtful and well-crafted comedies that tackle relatable themes with honesty and humor.
