Three European co-producers have joined Andrea di Stefano’s “Paradise Lost,” the thriller-romance starring Benicio Del Toro as drug lord Pablo Escobar.

Spanish distrib Alta Films, Barcelona-based Roxbury Pictures and Belgium’s Nexus Factory are set to co-produce the $20 million pic. Alta will distribute in Spain.

As first reported in Daily Variety (Nov. 15), “Lost” is being produced by Dimitri Rassam at Chapter 2. Frederique Dumas’ Studio Orange, the film arm of telco group Orange, and Pathe are co-producing and fully-financing the pic. Pathe has international sales and French distribution rights.

Josh Hutcherson toplines as a young American surfer who takes a trip to Colombia and falls madly in love with a beautiful local girl, played by Claudia Traisac. Their romance seems idyllic until he meets her uncle, Escobar.

Pic also stars Carlos Bardem (“Cell 211”), Brian Geraghty (“The Hurt Locker”) and French thesp Ana Girardot (“My Way”).

Rassam has assembled a crew that includes Carlos Conti, production designer of “The Motocycle Diaries,” Luis David Sansans, d.p. on “Days of Grace” and Maryline Monthieux, editor of “Gainsbourg: A Heroic Life.”

Lensing will start March 15 in Panama.

Chapter 2 has three productions due to hit theaters this year: “Gibraltar” (formerly known as “The Informant”), a crime thriller starring Gilles Lellouche and Tahar Rahim; “The Scapegoat,” a comedy with Berenice Bejo and Emir Kusturica; and Kirsten Dunst-starrer “Upside Down.”
