Passengers on a Seoul subway train are watching a short film.

In the movie, the Titanic is on the verge of sinking, but it regains balance when several pigs run to the stern.

The screening is part of the Seoul Metro and the Berlin Subway's joint international subway film festival.

The festival features 90-second short films that will be shown in trains or waiting rooms at subway stations.

The film festival opened on Thursday and will run through October fourth.
