Holed up in a Swiss-Italian hotel, Titta di Girolamo, the dour protagonist of Paolo Sorrentino’s leisurely thriller, seems like the last person on earth to be involved in criminal intrigue. Whether eyeing the hotel’s beautiful bartender with stony detachment or fighting bouts of insomnia with grim stoicism, he seems the essence of boring propriety. But we gradually discover that he’s a furtive junkie being pursued by members of the underworld. Toni Servillo’s portrayal of the chilly Titta is the film’s one unassailable asset. Unfortunately Sorrentino’s often playful assault on genre conventions is sabotaged by an ostentatious visual style that alludes to the work of such disparate directors as Antonioni and Scorsese but is little more than a bag of empty tricks. In Italian with subtitles.
