The couple, who married in 2000, announced their separation in 2017 after 18 years together, stating their priority was raising their children.
Stiller reflects on how his parents' 61-year marriage influenced his own, saying he felt like he couldn’t ‘live up to’ their relationship when he separated from his wife.
They reconciled during the Covid-19 pandemic after moving back in together with their children, which Stiller described as 'unexpected' and 'wonderful'.
The documentary premiered on 5 October at the New York Film Festival and will be available to stream on Apple TV+ from 24 October.
