Narcissus (Lithuanian: Narcizas) is a 2012 film written and directed by Dovilė Gasiūnaitė. In Greek mythology, Narcissus was a handsome young man, so vain that the gods condemned him to fall in love with his own reflection. Nowadays, Narcissistic personality disorder (NPD) is a pathological preoccupation with issues of self-importance, closely connected to ego-centrism.

In the original screenplay by Dovilė Gasiūnaitė, Teodore is a handsome and gifted string quartet cello player, who becomes increasingly obsessed with himself. His looks, sensitivity, and talent initially draw people in, but his lack of empathy and self-obsession hurt everyone around him. Teodore abandons his family, career, and friends in his quest for an unattainable challenge. His devastating battle takes place in the dark place of his own psyche.
