NATIONAL GALLERY is a documentary looking 'behind the scenes' at London's National Gallery.
There are three uses of strong language ('f**k') during a sequence in which a member of the public voices his disapproval of environmental activists demonstrating outside the gallery building. There is also a use of very mild bad language ('hell').
The film also contains images of nudity, battle violence and a figure being stabbed, all in the context of renowned classical paintings. There are some mild sex references and a comment about rape, also in the context of discussions about works of art.
Nudity is also seen as male and female models pose in life drawing classes.
