In Hollywood, auditions don’t always translate into the roles actors end up playing. Sometimes performers are brought in with one character in mind, only for casting decisions, chemistry reads, or creative changes to shift them into entirely different supporting parts. In many cases, those smaller roles go on to become standout moments in their careers, even outshining the original expectations of the audition process. Here, we look at ten actors who found themselves in exactly that situation.
Cillian Murphy

Cillian Murphy’s first encounter with Gotham came through an audition for Bruce Wayne in “Batman Begins.” He even screen tested in the Batsuit worn by Val Kilmer, an experience that quickly made clear he wasn’t being lined up to play the Dark Knight.
Christopher Nolan, however, saw something else entirely in his performance and shifted him into the role of Dr. Jonathan Crane, better known as the Scarecrow. That decision not only gave the film one of its most unsettling villains, it also marked the start of a long-running collaboration between Murphy and Nolan that would continue across multiple projects.
Tom Hiddleston
Before becoming one of the Marvel universe’s most recognizable villains, Tom Hiddleston actually stepped into the audition room aiming for something very different.
He originally read for Thor in the 2011 film, committing fully to the transformation with a blonde wig and intense screen tests that included wielding Mjolnir. After three months moving through the casting process, Marvel ultimately shifted direction and saw something in him that fit the role of Loki far better.
Sebastian Stan
Sebastian Stan initially auditioned for the role of Steve Rogers in “Captain America: The First Avenger,” going through the same early casting process as others considered for the lead. While he didn’t end up being cast as Captain America, the filmmakers saw something in his screen tests that stood out in a different way.
He was later brought back as Bucky Barnes, Steve Rogers’ closest friend, a role that would expand significantly as the character evolved into the Winter Soldier across the Marvel saga.
Tom Felton
Tom Felton went through the early “Harry Potter” casting process aiming much higher up the hero ladder than where he eventually landed. He auditioned for both Harry Potter and Ron Weasley, even trying on the look for Harry with glasses and a wig during his screen test.
Although he didn’t fit either of the two central boys in the way the filmmakers were envisioning them, he left a strong enough impression that he was kept in mind for something else entirely. That opportunity came in the form of Draco Malfoy, a role he ultimately secured after telling Chris Columbus during his audition for the character that he had read the books, a detail that wasn’t true. The director instantly knew he was lying, and there was something about that mischievous charm that made Felton the perfect choice.
Iwan Rheon
Iwan Rheon was very close to stepping into one of the “Game of Thrones” most iconic roles, having auditioned for Jon Snow and making it all the way to the final round of consideration. The part ultimately went to Kit Harington, but Rheon later confirmed he was one of the last two actors in contention, meaning the decision came down to a tight final choice.
Instead of the brooding hero of the North, he later returned to Westeros in a very different capacity, being cast in season 3 as Ramsay Bolton, the sadistic character who would go on to become one of the show’s most notorious villains.
Amanda Seyfried

Amanda Seyfried originally stepped into the “Mean Girls” casting process with her sights set on the top of the Plastics hierarchy, auditioning for the role of Regina George after flying to Los Angeles for the test.
She was in the mix for the film’s central antagonist, but the filmmakers ultimately chose Rachel McAdams, whose screen presence brought the kind of commanding energy they were looking for in Regina. Seyfried didn’t leave empty handed, though, and was soon offered the role of Karen Smith instead, rounding out the trio in a part that became an instant pop culture staple.
James Franco
James Franco first entered the “Spider-Man” casting process with the same goal as many young actors at the time, taking a shot at Peter Parker in Sam Raimi’s 2002 film. The role ultimately went to Tobey Maguire, whose interpretation defined the character for a generation, but Franco’s audition still left an impression on the filmmakers.
Rather than stepping away from the project, he was brought back into the world of Peter Parker as Harry Osborn, the best friend whose relationship with Spider-Man would become increasingly complicated as the trilogy unfolded.
Ashley Greene
Ashley Greene went through multiple rounds of auditions for “Twilight,” initially reading for Bella Swan and even taking part in chemistry tests as the production searched for its lead. Despite being brought back several times, she was ultimately told she wasn’t the right fit for Bella.
Instead of leaving the project behind, she was encouraged by casting directors and filmmaker Catherine Hardwicke to audition for Alice Cullen, a role she pursued through additional callbacks before finally landing it. Looking back, she has said she was relieved not to carry the pressure of the lead and felt the supporting role suited her at that stage of her career.
Lee Pace
Lee Pace confirmed he was in the running for Peter Quill in “Guardians of the Galaxy” after auditioning for Marvel in 2012, joining a competitive shortlist of actors being considered for the role. At the time, he spoke about being excited to meet with the studio and said he was drawn to the script, which placed him among other notable contenders like Joel Edgerton, Eddie Redmayne, and Jim Sturgess.
The part of Star-Lord ultimately went to Chris Pratt, but Pace didn’t leave the project behind. Director James Gunn later brought him back into the film as Ronan the Accuser, giving him the role of the primary antagonist instead of the galaxy’s unlikely hero.
Rainn Wilson

Rainn Wilson was the very first actor to audition for “The Office” and initially read for Michael Scott, hoping to land the show’s central role. He has since admitted that the audition didn’t go well, largely because he leaned too heavily on Ricky Gervais’ performance from the UK original instead of finding his own version of the character.
Although Michael wasn’t the right fit, the casting team saw something in his presence that stood out, and he was later brought back and offered the role of Dwight Schrute. What started as a misfired attempt at the lead ended up becoming one of television’s most memorable supporting performances.
