Real plot, not The Skin I live in adaptation

Los abrazos rotos is not the adaptation of a novel, is a original script from Almodovar. From Variety:

"Abrazos" is set in the '90s and present day. It will mix stylistic references to films such as Nicholas Ray's "In a Lonely Place" and Vincente Minnelli's "The Bad and the Beautiful" with signature Almodovar themes: "Fate, the mystery of creation, guilt, unscrupulous power, the eternal search of fathers for sons, and sons for fathers," Pedro Almodovar told Daily Variety.
More than one option

Echoing traditional financing practices on Almodovar movies, the brothers aim to pre-sell a small clutch of foreign territories to long-term distributors of Almodovar film, said Agustin Almodovar.

"Penelope (Cruz) will exchange the era's aprons, cardigans and the hairdos for an updated look, but one that mixes the transparent turbulence of Gene Tierney and the mistreated, challenging beauty of Linda Darnell in Otto Preminger's 'Fallen Angel,' " Pedro Almodovar explained, talking about points of departure for the film.

He is completing the screenplay. "Like some of my other films -- 'Women on the Verge of a Nervous Breakdown' -- this film came easily, in one go," Almodovar said.
