With its inspired casting, “Is This Thing On?” is strongest in its personal self-discovery journey as a married couple divorces.

Alex and Tess Novak (Will Arnett, Laura Dern) were married for 20 years and dote on their two boys, so co-parenting isn’t an issue, but navigating the single life is a bumpy path. Tess finds purpose again rejuvenating her athletic career while Alex stumbles onto comedy as therapy.

While how funny Alex is can be debated, the use of humor to get through life’s toughest times is a spot-on assessment. After all, Charlie Chaplin famously said: “Life is a tragedy when seen in close-up, but a comedy in long-shot.”

Frustrated by life’s ups and downs, Alex seeks a sense of purpose while he is frustrated by life’s ups and downs.. In stand-up comedy routines, he finds out he’s relatable as a middle-aged guy navigating ‘uncoupling.’ It’s also therapeutic for this sad dad. An interesting by-product is he learns more about himself.

Tess, who clearly wanted to divorce, sought to renew that zest for life she had as an Olympic volleyball player and college coach. After years of sacrificing for her family, she is loving getting back in the game. 

As Alex’s newfound hobby takes flight , he keeps it hidden from Tess, his friends and family. But he also has a re-energized outlook on life, and finds this outlook rewarding in ways he never imagined.

As they face middle age and divorce, the Novaks are working on co-parenting and their identities as singles. Somehow, they come to an understanding that surprises both, as they learn new things about each other.

This film is inspired by the real-life story of British comedian John Bishop. Arnett met him on a canal boat in Amsterdam and, after hearing about how he got his start in stand-up comedy, Arnett wanted to make it into a film.

Arnett, a very funny Emmy-nominated actor who broke out as “Gob” Bluth on “Arrested Development,” has carved a niche in voice-over work, especially in animated series and films (“BoJack Horseman,” “The Lego Batman Movie”).His is best known as the guy enticing us to eat Reese’s peanut butter cups every Halloween. 

Showing a new side to his capabilities, he is appealing as the befuddled and vulnerable Alex, while Oscar winner Dern is a good scene partner. Their dynamic is believable, both eliciting empathy. 

The film is directed by Bradley Cooper, his third feature, and it’s quite a departure from “A Star Is Born” and “Maestro” – an intimate interpersonal drama-comedy that amplifies relationship struggles that many people face.

In a supporting role, he’s practically unrecognizable as Alex’s best friend, Balls – a scruffy, vain actor in a rocky marriage to Christine (Andra Day), who is friends with Tess. The friends’ scenes seem to pad the film unnecessarily, and Sean Hayes and his real-life husband Scott Icenogle are seen only briefly as pals.

Nevertheless, the family scenes are heartfelt and humorous without strained effort. Terrific character actors Christine Ebersole and Ciaran Hinds lend lived-in credibility to their roles as Alex’s parents, who are close to Tess and their two grandchildren (Blake Kane as Felix and Calvin Knegten as Jude, both naturals).

The appearance of Peyton Manning as Laird, an old friend of Tess’, is a surprise, and he handles playing a character quite well. 

The script, written by Cooper, Arnett and Mark Chappell, captures the fast-paced, competitive standup comedy scene, particularly at the iconic venue the Comedy Cellar. 

Stand-up comics Chloe Radcliffe, Jordan Jensen, Reggie Conquest, Amy Sedaris and Elizabeth Furiati are an authentic part of the cast.They know that making people laugh during dark times is an elixir. 

The grittiness of New York, how both worlds felt real, the sincerity of lessons learned, and an in-sync score add to the film’s enjoyment. However, “Is This Thing On?” never rose above OK, despite its good intentions and amusing, relatable moments.
