Time Out says
From June through September, more than 240 movies will screen in parks all over Chicago as part of the city's annual Movies in the Parks program. From recent blockbusters like Maleficent and Gravity to classics like E.T. The Extra-Terrestrial and Space Jam, you're sure to find good something to watch (for free!) beneath the stars this summer.
Screenings typically begin at 8:30pm each evening. Take a look at the full list of movies and participating parks.
