Zero Moustafa is the lobby boy trained by M. Gustave in Wes Anderson’s The Grand Budapest Hotel.
Played by Tony Revolori, Zero arrives at the Grand Budapest Hotel and becomes the apprentice of Monsieur Gustave H., the hotel’s legendary concierge. Gustave teaches him the routines of service while involving him in the increasingly dangerous aftermath of a wealthy guest’s death and inheritance dispute.
The film uses several nested time periods and narrators. An older Zero, played by F. Murray Abraham, recounts the hotel’s history to a younger writer, played by Jude Law. Revolori portrays the younger Zero during the main adventure, creating a clear link between the hotel’s glamorous past and its later decline.
Zero is not the same character as Agatha, played by Saoirse Ronan, who is his partner and helps him during the plot. Another frequent confusion concerns Dmitri, Adrien Brody’s hostile heir, whose surname belongs to the wealthy family at the center of the conflict.
