The movie "La La Land" was a hit by pretty much every measure — it grossed more than $150 million at the domestic box office, took home six Oscars (not "Best Picture," but still), and L.A. Mayor Eric Garcetti even declared a "La La Land" Day.

But possibly the most important marker of success? "La La Land" now has its own drag parody show.

It’s a play called “So Long Boulder City,” presented by Celebration Theatre at The Lex in Hollywood. It imagines what the one-woman show in "La La Land," starring, written and directed by Emma Stone’s character, Mia Dolan, might have looked like.

In "La La Land," you see only a few glimpses of the "So Long Boulder City" set, one page of the script, and the meager audience turnout. The flop causes Mia to quit acting and break up with her boyfriend Sebastian, played by Ryan Gosling. But it also launches Mia's movie career, when a casting agent sees her performance and tracks her down.

Two veterans of the Groundlings Theatre Company, Jimmy Fowlie and Jordan Black, decided to fill in the blanks. It all started with a question Fowlie posed on Facebook:

Fowlie enlisted the help of his friend Jordan Black to co-write and direct the play. The two started by watching the film a few times to pick up any clues they could about Mia's show.

"Since it was called ‘So Long Boulder City,’ we knew it had to do with her leaving home and coming to Hollywood," Black says. "So we were just picking up all those little breadcrumbs and then we just exaggerated them from there. But I feel like even if you didn’t see the movie, there’s still plenty in the show to make you laugh, 'cause it’s really just a send-up of one-person shows is really what we’re doing."

A few achingly long on-stage costume changes, a failed attempt at improv, and a 4 1/2 minute performance of the "Electric Slide" help give the show some of its "so bad it's good" charm.

"I’ve been to these shows where you see someone who’s so delusional," Black says. "But yet they have this insane level of confidence to back it up. And that’s the Mia Dolan in our show — that character. That is really what drives her. She has this unearned confidence, which is really kind of admirable."

And luckily for Black and Fowlie, their version of "So Long Boulder City" hasn't been a flop like Mia's. After performances started selling out, Celebration Theatre added additional show times and now there's even talk of taking the play to New York City.

"The movie was so beloved and people took it very seriously because it was a throwback to the old musicals of yesteryear," Black says. "And then all of a sudden you have Jimmy's show. It's just a release and a relief to make fun of these things that everyone's taken so seriously."
