"Heart of the Warrior" / "El corazón del guerrero" (Spain 2000). This is a wild ride, like "Mazes and Monsters", but told from the perspective of the RPG character, with good special effects, settings and a very good soundtrack.

Ramon is your typical nerdy teenage boy in Madrid who likes to dream himself away playing DnD-style roleplaying games and imagines himself being Beldar, the barbarian warrior, fighting alongside his companion Sonja.

Unless the story is about Beldar, a barbarian warrior, who gets wounded while trying to steal a valuable gem - the Heart of the Warroir - and wakes up in the body of a meek teenage boy in Madrid; with his companion Sonja being a prostitute, not aware that she's in reality a warrior like him. Both of them seem to be hit by a curse that banished them to this strange world of refrigerators and cars and roleplaying games...

As I said, the movie is a well made wild ride between what's real and what's imagined; what may be a conspiracy or a real curse; or just a DnD fantasy in an insane mind...
