The free outdoor theater experience known as Movies at Center Park returns to downtown Chattanooga for three Saturdays next month.

Two of the titles are already set: "Finding Nemo" on Family Night, Sept. 20; and "Ghostbusters" for Finale Night, Sept. 27.

Still to be determined is the opening film for Viewers Choice Night on Sept. 13. Votes will be accepted online through Wednesday, Sept. 3, to see which of the following three films rises to the top:

• "The Breakfast Club," the 1985 "Brat Pack" film about high-schoolers from different cliques learning just how similar they really are.

• "Dumb and Dumber," the 1994 odyssey of two dimwitted friends trekking across America.

• "Field of Dreams," the 1989 classic about an Iowa farmer who hears voices that lead him to build a baseball diamond in his cornfield.
