Tucked almost out of sight under the arches of Waterloo Bridge, the British Film Institute contains four cinemas that screen thousands of films each year (many art-house), a gallery devoted to the moving image, and a mediatheque where you can watch movie and TV highlights from the BFI National Archive.
The BFI is the major venue for the BFI London Film Festival, which screens some 300 films from around the world each October.
