During a production's preview performances, an approximate running time will be added to that show's webpage.
Click the What's on link above, select the show you are seeing and the running time will be in the top left of the page.
The majority of productions at the NT have an interval, which usually lasts for 20 minutes. If a production does not have an interval, it will be shown alongside the running time on the show page.
The interval is normally midway through the play.
If you need more specific timings, please contact the box office.
