The theater chain previously offered screenings of the first and second presidential debates at select locations across the country.

"After the success of airing the last debate, including many full auditoriums, we want to continue to encourage our local communities to be engaged in public policy and provide Regal guests the unique opportunity to experience the political process on the big screen," said Steve Bunnell, chief content and programming officer at Regal Entertainment Group.

Guests are offered free entry as well as a free small soda with any popcorn purchase.

Tickets are available at the box office only.

The final debate, which will take place at the University of Nevada-Las Vegas, airs Oct. 19 at 9 p.m. ET.
