The filmmaker was promoting his new sci-fi movie Arrival at the Venice Film Festival in Italy on Monday (05Sep16) when he was asked about the follow-up to Ridley Scott's cult 1982 film, which has been shrouded in secrecy since shooting began.
Denis wasn't about to give anything away but he did tell Reuters, "It's an insane project that is moving forward... We are in the middle of the shoot right now and Ryan Gosling is fantastic.
"For me it's a big, big, big... artistic encounter... I have never been that inspired by an actor... He is really doing something special in front of the camera right now."
The film, which is set for release next year (17), also features Jared Leto, Robin Wright, Ana de Armas, MACkenzie Davis, and Harrison Ford, who will be reprising his role as robot hunter Rick Deckard from the 1982 original, based on Philip K. DICk's novel Do Androids Dream of Electric Sheep?
Gosling has previously been asked about the film, and joked the movie will actually be a star-studded musical, packed with dancing girls and Broadway-style tunes.
He quipped, "I am singing and dancing in it and you probably won't want to see me do that again! Most of the dance numbers are on practical locations but there's one where we had a whole freeway overpass for a day and people were dancing on cars and it was pretty amazing."
On a more serious note, Gosling said he had been sworn to secrecy about the Blade Runner sequel, adding, "There's literally a sniper on that roof if I say anything about Blade Runner."
