Lua de Cristal (English: Xuxa in Crystal Moon) is a 1990 Brazilian romantic comedy film directed by Tizuka Yamasaki, and starring Xuxa Meneghel. With just under 5 million spectators, Lua de Cristal was the biggest film of the 1990s, and it guaranteed Xuxa a second box-office hit at a time when the Brazilian film industry had all but ground to a halt.
