“Is This Thing On?” is a 2025 comedy‑drama film, and when people ask “is this thing on cast” they are usually looking for the main actors and a quick sense of who plays whom.

Main cast

  • Will Arnett – plays a middle‑aged father whose marriage is unraveling and who stumbles into stand‑up comedy in New York.
  • Laura Dern – plays his wife, Tess, who is grappling with the sacrifices she has made and what life looks like after separation.
  • Stand‑up comics such as Chloe Radcliffe, Jordan Jensen, and Reggie Conquest appear as working New York comedians, giving the club scenes a more authentic feel.

What the title means

  • In stand‑up, “Is this thing on?” is a stock joke line comics use when they first grab the microphone or when their jokes are not landing.
  • In the film, the title also echoes the question of whether the couple’s relationship is still “on” or worth saving, tying the mic joke to the state of their marriage.

Quick scoop on the movie

  • The story follows a man who, instead of going to therapy, impulsively tries stand‑up comedy, discovering both a talent and a kind of rough therapy in being honest on stage.
  • Parallel to his journey, Tess explores returning to her old passion for volleyball and possibly coaching, as both partners rebuild their identities while questioning divorce.
