MEXICO CITY (AP) — Oscar-winning director Alfonso Cuaron published another full-page newspaper ad in Mexican newspapers on Monday asking the president for a series of public debates on reforms to the country’s state-owned oil industry.

The “Gravity” director called for at least three televised debate between experts, critics and representatives of President Enrique Pena Nieto.

Cuaron had published 10 questions about President Pena Nieto’s reform efforts on April 28.

The president’s office issued answers to those questions about how the reforms would benefit Mexicans and protect the industry from environmental or financial abuses.

The overhaul allows private companies to drill for oil and hold concessions for the first time since Mexico’s oil industry was nationalized in 1938. Enabling legislation must still be passed.

Cuaron wrote that Monday’s ad would be his last on the issue.
