I helped my father end his own life. He helped me by letting me film it

The documentary maker Ondi Timoner explains why, having followed impossible visionaries' in movies such as Dig!, it made sense to record her father's final days

Last year, I made the most personal film of my career, about my father Eli's death. In January 2021, aged 92, Dad was in hospital, bedbound, with no prospect of recovery. My mother was struggling to cope. The only option appeared to be going to a facility for his remaining months.

I've been a film-maker for 30 years and have always dreamed of telling my father's story. I tend to make films about characters I describe as impossible visionaries": people with a singular vision who sometimes act impossibly to try and realise it - and to withstand the doubt and ridicule they incur.
