'The Engagement is a complex and fascinating love story set in contemporary London. Dario is a mysterious motorbike courier who falls in love with a girl who is engaged to be married, but he cannot escape his horrifying experiences as a Serb paramilitary in the Bosnian war.'

On dating the film:
The British Council dates the film to 2003 and, since their record of this film was last updated in 2005, there is no explicit reason to question this date. Other sources (including the Internet Movie Database) date the film to 2011. It is possible that the film had a delayed release but, as of this date, the reason for the discrepancy in these sources has been traced.
