An Oscar-nominated and Emmy-award winning director and activist is set to make an Ohio State appearance.

Josh Fox — who is known for his 2010 documentary “GasLand” and its 2013 follow-up “Gasland Part II” — is slated to speak to students Oct. 23 at 7:30 p.m. in the Performance Hall of the Ohio Union in an event sponsored by the Ohio Union Activities Board.

“Gasland” exposes the issue of hydraulic fracturing — or “fracking” — for natural gas in the United States and its effect on the environment. The controversial film was nominated for an Oscar for Best Documentary, features, in 2011 and won the Primetime Emmy award for Outstanding Directing for Nonfiction Programming.

“Gasland Part II” explored the gas industry’s portrayal of natural gas domestically.

OUAB announced the event via its Twitter account, @OUAB, Tuesday evening.

No tickets are necessary for Fox’s appearance, and the lecture is open to Columbus campus students only.

OUAB is a student organization that plans events using the university’s $37.50 student activity fee. More than 50 percent of the estimated $4 million in student activity fee revenue is allocated to OUAB.
