No need to introduce Viggo Mortensen, the multi-award winning actor, whose most recent accolade was a career achievement Donostia Award at the San Sebastian Festival last month. But the Lumière classic film festival in Lyon was a chance to get up close and personal with Mortensen, the director, at a masterclass in the intimate Comédie Odéon theater.

Switching comfortably between French, English and the occasional Spanish – Mortensen lives in Madrid – the actor-turned-director answered openly to the questions put to him.

Mortensen’s debut, “Falling,” is among 23 films originally selected to premiere in Cannes that will be screened at this edition of Lumière, whose director, Thierry Frémaux, also runs the Cannes fest. It tells the story of John, a gay man whose conservative and homophobic father starts to exhibit symptoms of dementia, forcing him to sell the family farm and move in with John and his husband. Asked how autobiographic the film is, Mortensen said that while he was inspired by his own parents’ illness, he wanted to show the world from the point of view of the person suffering from dementia.

“Most movies about people with dementia show them as confused, but in reality the people who are confused are those on the outside. The one who thinks it’s 1956 and he’s making love to his wife – he’s not confused, he’s there, that’s his present,” said Mortensen. “It was a very short shoot – just five weeks – and I wanted a library of pictures from different seasons to use as a memory for this person. I wanted to find a way of showing this (reality) through image and sound, that was the challenge for me.”

How did he prepare for the film?

“Making movies is about solving a series of problems that don’t end until the

LUCERNE, Switzerland (Reuters) – South Korean carmaker Hyundai on Wednesday presented the first seven hydrogen-powered trucks to customers in Switzerland, out of 50 such vehicles scheduled this year to bring zero-emission commercial vehicles to European roads.

For long haul, proponents say hydrogen-powered trucks have an advantage over electric rivals as they have a greater range and require less charging times but their uptake and mass production has been slow because they are expensive.

However, a McKinsey study in January said that once relative efficiencies of the power sources and lifetime costs of a truck are factored in, green hydrogen could reach cost parity with diesel by 2030.

Hyundai has been partnering with Swiss companies to build a value chain covering the production of green hydrogen from hydropower, hydrogen charging stations and the service and maintenance of the trucks.

The customers, which include supermarket chain Migros, will be leasing the trucks from Hyundai Hydrogen Mobility (HHM) to transport goods around the country, backed by the new hydrogen infrastructure.

Leases are on a pay-per-use basis that does not require an initial investment. Hyundai plans to put 1,600 trucks on Swiss roads by 2025.

Its H2 Xcient trucks have a 190 kilowatt fuel cell stack and seven high-pressure tanks holding 32 kgs of hydrogen, giving them a range far further than comparable vehicles powered by electric batteries on the market now.

HHM was set up by Hyundai and Swiss startup H2 energy last year to partner with Hydrospider, a joint venture of H2 Energy, industrial gas maker Linde and Swiss power utility Alpiq.

Hyundai plans for production capacity of 2,000 units of Xcient fuel cells per year by 2021 to support its expansion plans as demand for clean transport grows.

It views Switzerland as a test case for hydrogen fuel cells in heavy
