Supernova is the moving story of Sam (Colin Firth) and Tusker (Stanley Tucci), who after Tusker’s dementia diagnosis travel across England in an RV to visit family, friends and places from their past.    For Writer-Director Harry Macqueen, an enormous amount of research went into ensuring he did justice to the subject of dementia. “I think the key thing for writing this script really was several years of spending time with people who were living with this kind of dementia… Not only did I learn a huge amount about the medical side of dementia and the biology of it… but also, very, very importantly, the human element of it.”   Harry discusses his writing process, how to develop complex characters while maintaining simplicity of narrative, and how important it is to have a close group of friends you can share your work in progress with. “I really think that filmmaking and scriptwriting is not about ego at all… it's about taking responsibility for the project, [and] for the script.”   Supernova is now available on VOD.   Don’t forget to subscribe to the Write On Podcast on iTunes!
