Although Louis was initially starstruck by Millie during their first meeting, the pair eventually became friends during filming. "We'd be talking on set and joking and doing whatever . . . acting with Millie . . . made me sort of forget where I was," he said in a recent interview with MTV. When asked by I-D what it was like working with Millie, he responded, "Having her as a friend gave me a sort of freedom to try new things, because I knew if I did something wrong she would just laugh and it would be fine."
