SINCE THE SLAYING of Tejano singer Selena in March, Hollywood has besieged her family for rights to make a movie about her life. Last week, her father, Abraham Quintanilla, ended speculation about his daughter's biopic, announcing that Esparza/Katz Productions (Gettysburg) will produce the $15 to $20 million film along with the family's Q Productions. ''I chose [Moctesuma] Esparza because he's in tune with our culture,'' says Quintanilla, who will be the mo vie's executive producer. Many Latino filmmakers, from Luis Valdez (La Bamba) to Edward James Olmos (American Me), were considered to direct, but the family chose Gregory Nava (Mi Familia/My Family).
According to a source, Olmos may play Quintanilla; Esparza says that he's spoken with Salma Hayek (Desperado) about testing for the lead but notes that Selena's family will have a say in the decision. Whoever she is, says Quintanilla, who is planning to write a book about his daughter, ''she'll have to sing.'' Esparza hopes to begin production by early '96.
