Most of the time, actors either audition for a role or are offered it directly. Sometimes, however, the process they have to go through to land a part is a little...unorthodox.

Here are 17 actors who went above and beyond to land a role:

In order to land the lead role in Madonna's self-directed biopic, Julia Garner had to go through a grueling audition process that's been dubbed "Madonna boot camp." It reportedly involved 11-hour sessions with the pop star's choreographer, on top of more dance, reading, and singing sessions with Madonna.

Julia beat out actors like Florence Pugh, Alexa Demie, and Emma Laird for the part.

However, Universal Pictures reportedly scrapped the biopic after Madonna announced her upcoming world tour.

For Armageddon, Ben Affleck had to get $20,000 worth of dental work done because director Michael Bay "always liked low shots that kinda come right under your chin and make you [look] a little bit heroic," but he thought the actor "kinda had these baby teeth."

On the Armageddon DVD commentary, Michael said, "Jerry [Bruckheimer, the producer] used a very famous star in a plane movie that he replaced teeth with, so he said, 'We did it to him, why not do it to Ben?' So my dentist had Ben sitting in a dentist's chair for a week, eight hours a day."

When Jada Pinkett Smith first met producer Danny Cannon for her Gotham audition, she "went method" by showing up in character as Fish Mooney. She wore a short wig and a long gown, and she had a shirtless young man on a leash. He also had "LIAR" scrawled across his forehead in lipstick.

When Jodie Comer had her callback for Killing Eve, her future costar Sandra Oh brought in props for their eight-page scene — including a blueberry pie. Since the pages called for her character, Villanelle, to be eating, Jodie had consumed half the pie by the time they were done.

She told BUILD Series, "[Villanelle] loves life, and I think she loves her food ... but yeah, I felt a little bit sick when I left that audition."

When Lin-Manuel Miranda was considering Andrew Garfield for Tick, Tick... Boom, he asked Greg Miele, his massage therapist who's close friends with Andrew, if the actor could sing. Lying, Greg insisted he had an incredible voice and then called Andrew, who threw himself into singing and piano lessons for a year.

An hour before her final audition for The Illusionist, Jessica Biel bought a 19th-century princess outfit, then showed up "fully decked from head to toe."

She told the Chicago Tribune, "And it worked. I thought, Either I'm gonna be totally laughed at or they're gonna love it. One or the other. And I have no inhibitions at this moment and put it out there. And I walked in and I think there was a little shock at first and a little bit like, 'Oh god, no.' And then Michael London said, 'Oh, thank god. At least we have one costume out of the way.' It put me at ease. I was like, 'Awww. You love it. OK.'"

At the suggestion of Hugo's casting director, Chloë Grace Moretz lied to director Martin Scorsese and told him she was British. She made up an entire backstory about growing up in Cambridgeshire with parents who were horse breeders.

On The Late Show With Stephen Colbert, she said, "I ended up booking the part, and it wasn't really until much later in production that he realized I was not British. ... I think my mom's Southern accent kind of gave the whole 'horse breeding' [thing] away."

When Idris Elba auditioned for The Wire, he followed casting director Alexa Fogel's advice and pretended to be American because series creator David Simon didn't want to cast non-American actors.

However, when Idris came in for his fourth audition, he felt the need to come clean.

On Hot Ones, he said, "My parents told me not to lie — you gotta look someone in the eye and be honest."

For his Midsommar self-tape, Vilhelm Blomgren was instructed to walk 30 meters into the woods before starting the scene.

Brian d'Arcy James "wanted to do everything [he] could to get" a part in First Man, but they were having a hard time envisioning him as an M15 pilot. So he borrowed an Air Force jumpsuit from the Dark Phoenix costumer, borrowed a plane from his friend David Turner, and did a photo shoot to show the casting directors.

Brian told Backstage, "Long story short, [David] was able to help me get a friend of his who owns an airport, and who strangely also ha
