"Transsiberian", directed by Brad Anderson (2008)

If you like a jolly good thriller, then this film is for you. It tells the story of a young couple travelling by train from Beijing to Moscow who get involved with another young, globe-trotting pair, who it turns out are transporting drugs. The Russian police are on their trail, but they are also in the pay of the drug dealers.
The movie was beautifully filmed, mostly in Lithuania, with Woody Harrelson and Emily Mortimer in the lead roles, and Ben Kingsley as the corrupt police detective.
Not a huge box-office success but a film I enjoyed enough to recommend it !
