It was shot on a tiny budget with the cast using their own cameras. Charlie Day described them as reportedly "a bunch of kids with cameras."

Day, Howerton, and McElhenney crossed paths auditioning for projects in New York and Los Angeles. Day and Howerton reportedly bonded on a car ride back from testing for That ’80s Show in late 2001.
What was the original idea for the pilot?
McElhenney conceived a scenario where a friend visits another to ask for sugar, the host reveals he has cancer, and the visitor only cares about getting the sugar. That awkward setup became the foundation for the show’s humor.

It is a musical episode that became so popular it spawned a live stage tour across six cities in 2009. Howerton described the tour as an expanded version with new songs and room to improvise.

Yes. It had a two-episode crossover event with Abbott Elementary that aired in January 2025, and a Russian adaptation called It’s Always Sunny in Moscow premiered on TNT in 2014.
What is the show’s signature comedic style?
It often pairs genteel big-band orchestral music with deeply immoral and depraved behavior. Day said this juxtaposition works by "disarming the audience."
Has the show won major awards?
Despite critical praise, it has notoriously avoided major Emmy recognition, a running joke among fans. In 2019 the BBC called it the best US sitcom.
