Paris-based sales banner Loco Films has snatched up “Don’t Call Me Son” (Mae So Ha Uma”) by critically-acclaimed Brazilian helmer Anna Muylaert in the run up to its world premiere at the Berlinale Panorama.

“Don’t Call Me Son” marks Muylaert’s anticipated follow-up to “The Second Mother,” which won Sundance’s jury prize, Berlin’s Panorama’s audience award and traveled to over 30 territories, becoming one of last year’s biggest world cinema hits.

Exploring motherhood, youth and identity, “Don’t Call Me Son” follows Pierre, a teenager who discovers his mom is not his biological mother and has to move in with his real family. As he changes homes and his own name, the young man starts to wonder about his real identity.

Matheus Nachtergaele (“City of God”), Dani Nefussi (“Smoke Gets in Your Eyes”) and Naomi Nero topline, along with Daniel Botelho, Luciana Peas, among others.

Pic is produced by leading Brazilian shingle Dezenove Som E Imagens and Africa Filmes. The key crew includes “The Second Mother” cinematographer, Barbara Alvarez.

Loco Films is currently attending Rotterdam where its TV drama “La Casa” by Diego Lerman (“Refugiado”) is world-premiering.

The sales company was launched in May 2015 by Laurent Danielou, former boss of Gaul’s Rezo Films, and Enrique Gonzalez Kuhn, former topper of Spain’s distribution shingle “Caramel.”
