Joan Lui (Joan Lui - Ma un giorno nel paese arrivo io di lunedì)

Adriano Celentano, the Italian singer and actor, both directed and starred in Joan Lui (full title Joan Lui - Ma un giorno nel paese arrivo io di lunedì), a 1985 musical comedy. Celentano also wrote the screenplay, edited the film, composed the music and sang the songs himself. Cecchi Gori Group produced it. It runs about 163 minutes and opened in Italy on 25 December 1985.

The story brings the second coming of Jesus Christ into the present day. Joan Lui, a singer who stands against the hypocrisy of Western culture, gathers young musicians to spread his message, and songs written and performed by Celentano carry the narrative. Alongside Celentano, the cast includes Claudia Mori, Marthe Keller, Haruhiko Yamanouchi, Sal Borgese, Francesco Salvi and Romano Puppo.

It was the fourth and last of the films Celentano wrote, directed and starred in, and the last film of Claudia Mori, who ended a 26-year acting career with it. The French coordinator Rémy Julienne handled the stunts. At roughly 20 billion lire it was one of the costliest productions in Italian cinema, with production and distribution problems. By the end of the 1985-86 season it ranked 23rd at the Italian box office, and it did better with audiences in Germany and the Soviet Union.
