The US Health Department criticised the study.

Sentimental Value was the big winner at the European Film Awards, which are regarded as Europe's Oscars.

Not only did it win European Film of the Year, but it was also successful in the categories of director, screenwriter, actress and actor.

The last going to Stellan Skarsgård, who also won a Golden Globe a week ago for his performance in the film.

For more on sentimental value, here's Tom Brook from a noisy red carpet scrum at the European Film Awards in Berlin.

It's a Norwegian film.

It's a family drama.

It deals with this strange father-daughter relationship.

And a lot of people have really actually taken to this film.

It's now become the most successful Norwegian film of all time.

And I'm sure when the Oscar nominations are announced on Thursday of the week that's coming up, it will get several nominations.

One of the best performances in the film comes from 74-year-old Swedish actor Stellan Skarsgård, who could make history conceivably by becoming the first Swede to win an acting Oscar in his category.

And I spoke to him on the red carpet not so long ago, asking him why this role was important for him.

It's about relationships within a family, and it's a remarkably quiet film in a way.

It's subtle, and it's about really dark subjects, but incredibly light.

It's like a souffle in a way.

But I think it's funny.

It's entertaining.
