MADRID — Argentina’s Martin Mauregui, a co-scribe on Pablo Trapero “Lion’s Den,” “Carancho” and “White Elephant,” is prepping his directorial debut, “1922.”

A Patagonia-set period drama, “1922” is set up at Buenos Aires’ La Union de los Rios, which Mauregui founded in 2011 with screenwriters-turned-directors Santiago Mitre and Alejandro Fadel, plus producer Agustina Llambi Campbell, all alums of Buenos Aires’ Universidad de Cine.

Written by Mauregui, “1922” turns on the friendship between two on-the-run laborers, against the background of Patagonia’s 1921 uprising by anarchists and trade unionists.

Mauregui will complete a first draft by August, Llambi Campbell said.

“Politics provides a context, but the film is really about friendship, fraternity, adventures,” she added.

“1922” will be Union’s third feature. It follows Mitre’s “The Student,” which won 20 kudos, including Locarno’s Special Jury Prize, and played Toronto and New York, and Fadel’s “The Wild Ones,” which scooped Cannes’ Critics’ Week ACID/CCAS Distribution Support Award. Both were shot on micro-budgets.

On “1922,” Union aims to tap traditional financing, such as domestic or international co-production, Llambi Campbell said. Budget will be around $1 million, above par for Argentina. Union’s partners will all produce.
