While everyone gets their coins together for Beyonce and Jay-Z’s On The Run II tour, there is a fact hidden in their promo posters that only true cinephiles would know.

As pointed out by Ejatu Shaw and reported by OkayAfrica, the posters reference the 1973 Senegalese film, Touki Bouki, directed by the iconic African director, Djibril Diop Mambéty.

His niece, Mati Diop, directed a 2013 doc titled Mille Soleils (A Thousand Suns), which explores the legacy of Touki Bouki and along the way gets to know Touki Bouki‘s two main actors (Magaye Niang and Mareme Niang) thirty-five years later.

Based on his own story and script, Djibril Diop Mambéty reportedly made Touki Bouki on a $30,000 budget. Often compared to films of the French New Wave, Mambety puts his stamp on a film that incorporates stylistic flourishes that were considered uncharacteristic of most African films at the time, emphasizing both the highlights and struggles with the hybridization of Senegal.

Touki Bouki originally premiered in Cannes in 1973. You can watch the film on full on YouTube below:
