Screenwriter and director Richard Curtis has explained the personal motivation behind what he says will be his final film.

About Time tells the story of a young man who discovers he can time-travel, and what he chooses to do with that power.

Curtis told BBC Breakfast that he was "trying to make a film about how we can treasure every normal day of our lives".
