Cinematographer and director Kirsten Johnson was afraid of losing her father to dementia, so she got in first, killing him off in imaginative and comical ways in her new film Dick Johnson is Dead.
It's a comedy but also a pre-emptive eulogy, documenting and celebrating the man her father was and is, as he gamely embraces the film-making process.
The film, which is available on Netflix, won "Best Documentary Feature" as well as "Best Director" at the Critics' Choice awards this week, and is tipped as an Oscar contender.
As a cinematographer Johnson has worked on many films including Citizenfour, The Oath, Pray the Devil Back to Hell, and Fahrenheit 9/11.
She also directed 2016's Cameraperson, an autobiographical collage of what she's witnessed during her career as a cinematographer
