Back to the Future Day is Oct. 21, 2015 — the day that Marty McFly and Doc traveled to in Back to the Future Part II — and there’s no better way to celebrate with a marathon of the three classic movies.

You can watch the movies at home or attend a marathon at the AMC Showplace 16 theater in South Bend.

Back to the Future will begin at 4:29 p.m. followed by Back to the Future Part II at 7 p.m. and Back to the Future Part III at 9:30 p.m.

Tickets are $3.99 a piece for each showing.

The theatre is located at 450 W. Chippewa Ave., South Bend.
