Starring alongside Oscar winner Olivia Colman and Aud Mason-Hyde, Lithgow plays a titular character in “Jimpa,” a father and grandfather who left his family behind in Australia years ago to move to Amsterdam and live as an openly gay man and activist.

ScreenRant speaks to Jimpa director Sophie Hyde, John Lithgow, and other stars about the intensely personal experience of making the film at Sundance.

Sundance: Colman plays a filmmaker struggling to reconcile her resentment toward her gay father in Sophie Hyde's thinly rendered portrait of generational divides.

That we’re watching John Lithgow go on about oral sex and Olivia Colman chatting about polyamory with her teenage child make the film that much odder.

Even alongside heavy-hitters like Lithgow and Colman, it is remarkable how effortlessly Mason-Hyde holds their own. In many ways, their scenes are what bring everything out that the adults are looking away from.

Sophie Hyde’s latest centers on a filmmaker navigating the cross currents between her nonbinary teenager and her hedonistic gay father while working on a project about the end of her parents’ marriage.
