Apple TV+ bills “The Studio,” its Seth Rogen-led skewering of the Hollywood studio system, as a “comedy.” It is also, according to the show’s costume designer, Kameron Lennox, a fantasy.

“These characters are trying to hold on to this old love and passion of what filmmaking was and should be,” Ms. Lennox said. “But we’re losing that sense.”

“The Studio,” which was created and directed by Mr. Rogen and Evan Goldberg, revolves around Mr. Rogen’s Matt Remick, a bright-eyed striver who has scratched his way into the chief executive’s seat at the fictional Continental Studios. Collectively, Mr. Remick and his royal court of department heads are smitten with a navel-gazing nostalgia for Hollywood’s golden age.

They end the days watching “Casino,” endeavor to greenlight anything other than reheated I.P. projects and kowtow to the many Hollywood aristocrats who appear on “The Studio” as exaggerated versions of themselves. (That the show airs on the very sort of streamer that helped upend the old Hollywood system adds its own layer of irony.)

And if the Hollywood of today is an expanse of executives in gray sweaters and thousand-dollar dress sneakers, that memo was lost on its way to “The Studio.” In his turmeric-colored dress shirts and blazers with lapels jutting out above his shoulders, Matt is a throwback to a time when studio moguls dressed more like Italian industrialists. (A time that may not have even really existed.)
