Harrison knows he’s Harrison Ford, and I knew it that day. I always had a conspiracy theory that he knew he was Harrison Ford, but people always say, “When you meet Harrison, he’s casual, he’s laidback.” And all those things he is…but at the same time, he knows who he is.
The breakthrough came when Boyega checked out Mark Hamill and Harrison
Ford’s original Star Wars auditions footage on YouTube and was surprised
by how stylised their performances were – even at that stage. He calls
it ‘Star Wars acting’: a heightened, more fun version of regular movie
acting. He also remembered Abrams telling him that his character Finn
could be anything he wanted. So Boyega upped the fun element of his
audition performances. And it proved successful.
