Director Daniel Roher's film 'Navalny' won the Best Documentary Feature Film award at the Oscars 2023.

According to Variety, a US-based news outlet, the documentary, directed by Daniel Roher, gained new relevance after Russia's unprovoked invasion of Ukraine in 2022. The CNN Films/Warner Bros. documentary is a fly-on-the-wall account of the rousing populist who was once a presidential candidate -- and posed such a threat to Putin that Navalny was poisoned in a botched assassination plot ordered by the Kremlin in 2020. Navalny was detained in January 2021 and currently is serving a nine-year sentence in a Russian gulag. He has spent much of the sentence in solitary confinement.
