Spanish sales house Film Factory Entertainment has nabbed worldwide sales rights to Jorge Torregrossa’s debut “Fin” (The End).

“End” will be introduced to buyers at Toronto.

Three of Spain’s foremost production players team on “End”: Apaches Entertainment (“The Impossible”), Mod Producciones (“Agora”) and Spanish commercial broadcaster Antena 3’s film division Antena 3 Films (“You Will Meet a Tall Dark Stranger”).

“End” turns on a reunion of old friends, now in their 30s or 40s, who spend the weekend in a mountain log cabin. A strange, sudden incident leaves them with no means of communication to the outside world. Seeking help, the group disintegrates, just as a new natural world is revealed to their astonished eyes.

Cast is led by Maribel Verdu.

Two of Spain’s most sought-after scriptwriters have penned “End”: Jorge Guerricaechevarria (“Cell 211”) and Sergio G. Sanchez (“The Orphanage”). The script adapts David Monteagudo’s same titled best-selling novel.

Pic is in production, shooting in the Madrid and Valencia regions.

” ‘End’ is a thriller with decisive fantasy elements. People need original plot twists in genre movies, as in ‘End,’ which is undoubtedly one of the great Spanish productions of the year,” Film Factory CEO Vicente Canales told Variety.

Film Factory’s Toronto slate for Toronto includes: Gonzalo Lopez Gallego’s car-chase action movie “Inertia”; “Puzzled Love,” which has 13 directors; Juan Jose Campanella toon pic “Foosball”; and Eduardo Cortes’ “Winning Streak.”
