Kosar Ali plays Rocks's best friend Sumayra in the film, but it turns out that the pair are actually pretty good friends in real life, too. In an interview with The Guardian, Ali said that "me and Bukky, we're like this", miming them drawn together with her hands. She added that "she's at my house, like, three days a week. She's like a mum, a best friend, a sister and an auntie in one. The things her brain comes up with, I could literally sit there and have a conversation with her for six hours".
