Pulp Fiction and Mary Poppins are among the films to be added to the National Film Registry, Digital Spy said.

The registry is an ongoing collection of American films dating back to 1912 that are deemed "culturally, historically or aesthetically significant".

The list is updated each year with 25 new titles for preservation, selected by curators, members of the National Film Preservation Board and the public.

Michael Moore's Roger & Me, The Magnificent Seven, Judgment at Nuremberg and Who's Afraid of Virginia Woolf? are also among the 25 films added this year.

There are now a total of 625 films in the National Film Registry.

Other films added this year include 1956 sci-fi Forbidden Planet, John Wayne's The Quiet Man, film noir Gilda, and 1962 animation The Hole.

Silent movies The Virtuous Vamp and Daughter of Dawn are also added.
