Before Donald Trump was tearing down Mexicans and his fellow presidential nominees, he was demolishing buildings as a 1980s real estate developer. In a new film, Funny or Die gives us a view of that world, one filled with power, beautiful women and extravagance.

“The only thing with more brass is my balls,” says Johnny Depp, who plays Donald Trump in the 50-minute movie.

Released on the day of Trump’s victory in the New Hampshire Republican presidential primary, the film is presented as a lost adaptation of the tycoon’s 1987 best-selling business advice book The Art of the Deal (lessons include “Use your leverage!” “Maximize your options!” “Improve your location!” All of these are yuuuuuuge.) There’s an all-star cast—along with Depp, the movie features Alfred Molina, Patton Oswalt, Ron Howard, Alf and others. For the Funny or Die team, one of the biggest feats was keeping the entire project under wraps.

Two of the minds behind the Trump movie were Owen Burke, editor in chief at Funny Or Die, and Joe Randazzo, who wrote the script. They answered questions about the making of the film in a recent AMA.

Here’s what we learned.

The idea for Donald Trump’s The Art of the Deal started with Burke.

Much of the story is based on true Trump tales.

Johnny Depp was on board right away.

The whole cast was a dream.

Even Alf was a great choice.

There were a few challenges.

They had an extremely small window for filming.

Depp improvised the line “world-class Trump dump.”

Here’s the comedy show they’re referring to:

So far, the real-life Trump hasn’t responded to the film.

There could be films about other presidential candidates in the future. Maybe.
