This week Turner's FilmStruck is trending on Twitter with its #FilmStruck4 campaign.

The campaign, which asks social media's netizens to name four films that define them and tag friends to do the same, has FilmStruck everywhere on Twitter and brings welcome attention to our favorite classic-film streaming service.

Hollywood heavyweights like directors Judd Apatow, Rian Johnson, James Gunn and Guillermo Del Toro (who couldn't limit it to four films, natch); actors Jonah Hill, Gabrielle Union, Natasha Lyonne; and nearly a hundred internet influencers have hopped on the bandwagon, celebrating their favorite—and defining—films.

As the exclusive streaming home of the Criterion Collection and classics from TCM Select, FilmStruck offers access to critically acclaimed films and iconic movies from the Golden Age of Hollywood. It enhances the viewing experience with exclusive introductions, rare archival TCM content, and bonus material you’ll only find on FilmStruck.
