"i remember the day @melton told me about this project. we were still just friends then. he hadn’t even been cast yet. they hadn’t even started casting. all he told me was 'i’m going to play this role, i am daniel bae,'" Mendes wrote on Instagram of Melton being convinced he would play his Sun Is Also A Star character. "Aside from having the biggest heart out of anyone i know, his passion and tenacity are part of the reason i fell in love with him. watching him throw his entire heart and soul into this story of love taught me a lot about the kind of person he is."
