Bradley Cooper and Laura Dern shine on the red carpet of Is This Thing On?

Bradley Cooper plays Arnie, the best friend of the main character, a comedian in crisis played by Will Arnett. In addition to playing this secondary but significant role, Cooper also directs the film, which he co-wrote with Arnett and Mark Chappell. His character brings a balance of humor and gravity, acting as an emotional mirror to the hero.

The star of the Jurassic Park franchise plays Beth, the partner of the main character, played by Will Arnett. Her role brings an essential emotional dimension to the film: Beth embodies lucidity and tenderness in the face of the drift of the comedian she loves, oscillating between support and disillusionment.

American comedian Will Arnett stars as Alex, a comedian at a loss for direction who is trying to revive his career while navigating a chaotic personal life.

Singer Andra Day plays Naomi, a charismatic musician who crosses paths with Alex(Will Arnett) and becomes both a source of inspiration and a mirror for her own frailties.

John Bishop plays Danny, a fellow comedian and old friend of Alex’s, who represents both the camaraderie and rivalry typical of the stand-up world. With his biting humor and natural warmth, Bishop brings a touch of realism and humanity to the film, embodying the day-to-day life of performers faced with the wear and tear of the profession and the fear of oblivion.

Claudia Winkleman plays herself, a TV host who interviews Alex in a key sequence of the film. Her brief but powerful appearance serves as a narrative pivot, confronting the protagonist with the public perception of his decline and the superficiality of the media world.
