Movie title in article: literal translation?

I would definitely keep the original title, and if it was straightforward, but not recognisable to target readers, translate it literally, as you suggest.

E.g. English readers might not immediately recognise Lille Rødhætte in Danish as Little Red Riding Hood, but the literal translation would be fine.

Other titles with allusions or subtle hints about the story could be difficult. I might try to suggest in the context that there was more under the surface, but as others point out, it would be a mistake to invent a name for a film which later became known by another name.

Space available, how important it actually is and various other factors might play a part too.

I feel that the Scandinavian passion for translating TV series literally gives a wrong impression in English, but it is hard to suggest anything better - I would simply go for something completely different from

Kingdom Hospital - though that is perhaps just odd enough to fit...

The Killing (literally The Crime)
The Bridge

And so on.

There is no simple answer!
