CANNES — Elias Querejeta P.C. and sister company Esicma have sold “Assassination in February” to Colifilms in France. Pic unspools in Critics Week here.

Directed by Eterio Ortega Santillana and scripted by producer Elias Querejeta, “Assassination” is a documentary based on interviews with the relatives and friends of socialist politician Fernando Buesa and his escort Jorge Diez, who were murdered by ETA separatist terrorists in February 2000.

Pic is sure to cause a stir when it opens theatrically in Spain May 25, as it is one of the few recent films to touch on Basque terrorism and to portray the psychological horror of its consequences.

Elias Querejeta P.C. is in talks for sales on the pic to the U.K. and Italy. There have been preliminary conversations for a U.S. sales deal, Querejeta said.

The sales push on “Assassination” comes as Querejeta is prepping two new feature film projects: Fernando Leon’s $3 million “Mondays in the Sun,” co-written with Ignacio del Moral Garcia, and Gracia Querejeta’s “Hector,” co-scribed by David Planell.

“Mondays” is in pre-production, “Hector” at the script stage.

“Assassination” forms part of an ambitious agreement, struck last year, between Querejeta and satcaster Via Digital to co-finance six docs a year. So far seven have been completed. Via and Querejeta also are prepping docu series “Soccer and Architecture.”
