Steve Martin and Robin Williams once starred in Samuel Beckett's 'Waiting for Godot,' one of the most well-regarded examples of the existential movement called 'Theater of the Absurd.'

Samuel Beckett's 'Waiting for Godot' dramatizes existential absurdity

The play, originally staged in 1953, is notorious for its lack of action. For the most part, its two principal characters, Vladimir and Estragon, spend the majority of the play wondering whether a mysterious Godot will ever appear. By the end, Godot has still not arrived, yet Vladimir and Estragon do not move, a choice that reflects the existential notion that humans often hope in vain for meaning that does not exist.

The play, about being stuck, resonated with inmates. Critics noted that the incarcerated audience empathized with its hopeless characters much more than those at the show's North American premiere in Miami, who'd walked out in disgust.

'Waiting for Godot' was inspired by a Friedrich painting

Samuel Beckett was an admirer of art and, while touring German art galleries in 1937, saw Caspar David Friedrich’s Two Men Contemplating the Moon. A directorial notebook for the original production of “Waiting for Godot” notes that the end of the play’s first act was inspired by the 19th-century work.

Disillusioned mid-century playwrights, such as Samuel Beckett and Eugène Ionesco, brought existentialist ideas to the stage through the Theater of the Absurd.

Existential dread still informs popular comedies

Although the Theater of the Absurd was primarily a 20th-century trend, a similar kind of existentialist-minded comedy still exists in popular culture. Films like “Everything Everywhere All At Once” and television shows like “BoJack Horseman” tackle the same issues that existentialist thinkers like Sartre, Beauvoir, and Camus explored, transforming those profound questions into thought-provoking and crowd-pleasing works of comedy.

Steve Martin was vying for love on 'The Dating Game' before he was selling out arenas

In 1968, the 21-year-old Martin was a writer for the Smothers Brothers, who had a popular variety show. He appeared on “The Dating Game” as one of the bachelors, attempting to impress the twin sister of his childhood crush. (Spoiler: It worked.)

Steve Martin was a wildly successful stand-up—and abruptly quit doing it

In the ‘70s, few stand-up comics were bigger than Steve Martin, who released multiplatinum albums and regularly sold out arenas. As he detailed in his 2007 memoir, Martin had grown disillusioned with his success as a stand-up and pivoted into film.

Modern improv comedy, which eschews scripts and emphasizes listening, was developed by University of Chicago students in the early 1950s.

Camus directed a Picasso-penned play

The show, called "Desire Caught by the Tail," was written by Picasso in 1941 while living in Nazi-occupied Paris. It was first staged in 1944, featuring several French intellectuals, including Albert Camus, who directed, as well as Jean-Paul Sartre and Simone de Beauvoir, who had starring roles.

A blend of brilliance and humor made Stephen Hawking's cameos unforgettable

Throughout his life, he appeared in numerous pop culture moments—from "The Simpsons" to "The Big Bang Theory"—showing his talent for comedy and his love of science outreach. He was the only person to play himself on "Star Trek: The Next Generation," even writing some of his own lines.

Mel Brooks became an EGOT winner in 2001, meaning he's been awarded an Emmy, a Grammy, an Oscar, and a Tony.

Sartre staged his first play in a POW camp

While imprisoned by the Nazis, the French writer was given permission to write and produce a Christmas show for 15,000 of his fellow POWs. He took the opportunity to produce "Bariona, or the Son of Thunder," a Nativity play that subtly criticized his captors without arousing their suspicions.

Mel Brooks got his first big break in 1950 as a writer on Sid Caesar's 'Your Show of Shows,' a pioneering TV variety show.

Although not known for horror, a young Tennessee Williams wrote a gothic radio play

The "Streetcar Named Desire" author wrote "The Strangers," a short script, while a student at the University of Iowa in the 1930s. Andrew Gulli, managing editor for the literary magazine that published the unearthed piece, said that it blends classic '30s radio horror with themes Williams would revisit in later, more famous work.

The landmark opera 'Einstein on the Beach' was around 5 hours long with no intermissions, and the audience was encouraged to come and go as they pleased.

'Einstein on the Beach,' often considered a groundbreaking experimental work, is structured like a classical opera.

Mel Brooks got his start in comedy by accidentally flubbing a scene in a play and turning it into a fourth-wall-breaking joke, something that would later become a hallmark of his humor.

Camus and Sartre admired each other's work before becoming friends

The two writers, who would later be considered two of the biggest names associated with existentialism, wrote positive reviews of each others' early work, with Camus praising Sartre's novel "Nausea" and story collection "The Wall" and, later, Sartre favorably compared Camus' "The Stranger" to Franz Kafka and Ernest Hemingway. Still, their reviews included some critiques, hinting at the larger disagreements that would come much later.

Jean-Paul Sartre famously wrote that 'Hell is—other people'

The line appears toward the end of the play "No Exit." One character, realizing that he's confined to live out the rest of his days with the play's other two characters, exclaims, "There's no need for red-hot pokers. Hell is—other people!"

Auditions for the US adaptation of 'The Office' included many now-famous actors

When NBC decided to adapt "The Office" for American audiences, they auditioned in several comic character actors, including Seth Rogen, Bob Odenkirk, Kathryn Hahn, and Adam Scott. Though those actors didn't land the parts, they did end up with major roles in other critically-acclaimed movies and TV shows, including "Knocked Up," "Abigail All Along," "Better Call Saul," and "Severance."

One actor made a career out of playing Mark Twain

Hal Holbrook toured in the one-man show “Mark Twain Tonight!” for over six decades. In the performances, Holbrook wore Twain’s iconic white suit and offered witticisms similar to Twain’s famous lectures. Holbrook won a Tony Award in 1966 for a Broadway run of the show.

Brooks' Broadway adaptation of 'The Producers' was a massive hit when it debuted in 2001, and broke a record for most Tony wins.

Actors on 'All the President's Men' immersed themselves in real-world reporting

Dustin Hoffman and Robert Redford spent months shadowing the real Carl Bernstein and Bob Woodward—working at The Washington Post, living with Bernstein's family, and studying their mannerisms—to bring authentic nuance to their portrayals of Watergate's investigative journalists.

Simone de Beauvoir's lone play has mostly been overlooked

Although primarily known as a philosopher, Beauvoir wrote the play "The Useless Mouths," which debuted in Paris in November 1945. The work is about a government allowing "useless" citizens—women, children, the elderly—to starve during a food shortage. While it's not widely staged, some Beauvoir scholars believe it's a significant text that explores many of the existential themes she explores in her other work.

'Barbenheimer' resulted in a historic box-office event

The cultural sensation that erupted when Christopher Nolan's "Oppenheimer" and Greta Gerwig's "Barbie" shared an opening night was something that no one could have predicted. "Barbenheimer," as the pairing was called, became a semiserious litmus test for relationships: Who wanted to see which film, and in what order? The viral moment led to box-office gold for both movies, as well as a few Oscars.

'The Big Lebowski' slowly spawned a cult following—and a religion

When it was released in 1998, the Coen brothers' film didn't garner overwhelming critical praise or generate impressive ticket sales. Over time, though, it's become one of the defining cult movies, with midnight showings where audience members dress as Jeff Bridges' "Dude" and drink White Russians. It's even spawned its own religion: dudeism.
