Jaume Balagueró is perhaps best known for his popular cinema verite thrillers [REC] and [REC]2 (review), which was co-written and c-directed with Paco Plaza, and have since become tremendous hits among horror fans. While speculation concerning the potential for a [REC]3 continues, Shock Till You Drop has reported that Jaume Balaguero's solo directorial effort Flatmate has entered the pre-production stages and has announced its first cast member, Spanish actor Luis Tosar.

Tosar is most widely known for his role as the primary antagonist Montoya in Michael Mann's Miami Vice, though he sports an impressive list of roles from Spain, including last year's Cellda 211, for which he received a best actor nomination at the 2010 Goya Awards, which will be held on February 14th.

In addition to this little tidbit of info, Shock also brings to us an updated synopsis, expanding on the one they reported a few months back.
"Marcos works as a doorman in a Barcelona apartment building. happiness eludes him and he feels the need to reaffirm his reasons for living on a daily basis.

He goes about his day to day work mainly unnoticed by the residents of the building, but he pays close attention to them. He knows all the intimate details of their lives everything about them, especially one of them. Clara King is a happy-go-lucky young woman, who always looks on the positive side of things. Her cheery attitude to life makes Marcos' skin crawl. He won;t be happy until he has wiped that smile off her face once and for all, because Marcos feeds off of other people's pain. He delights in the unhappiness and anguish of others and he loves nothing more than to plant the seed of misery and watch it grow.

In Clara he found the perfect target, and he will go to extreme lengths to make her life miserable. But Marcos is starting to get a bit too cocky, and soon his carefully thought out plans will start to unravel. Lucky for him, he has one last ace up his sleeve."

Given Balaguero's impressive resume and uncanny ability to direct a taut thriller, I have high hopes for this one, which is written by Alberto Marini. The plot is unique, and if Tosar's creepy-as-Hell appearance is any indication of his ability to play what appears to be a raving sociopath (presuming this is the role for which he was cast), then we're in for a real treat.
