In 2009, "Dogtooth", directed by Yorgos Lanthimos, won the Prix Un Certain Regard at the Cannes Film Festival, and in 2011 was nominated for Best Foreign Language Film at the 83rd Academy Awards. The 2010 film "Attenberg", directed by Athina Rachel Tsangari, won the Coppa Volpi Award for Best Actress (Ariane Labed) at the Venice Film Festival. In 2011 "Alps" won the Osella Award for Best Screenplay (Yorgos Lanthimos and Efthimiοs Filippou) at the 68th Venice Film Festival. "Dogtooth", "Attenberg" and "Alps" are part of what some film critics, including Steve Rose of "The Guardian", have termed the "Greek Weird Wave," which involves movies with haunting cinematography, alienated protagonists and absurdist dialogue. Other films mentioned as part of this "wave" include Panos H. Koutras's "Strella" (2009) and Yannis Economides's "Knifer" (2010).
