The Screen on the Green summer movie series is showing its final movie of the summer.
The free outdoor movie festival on the National Mall concludes Monday with a showing of "Back to the Future," which will begin at dusk (around 8 p.m.).
Movie-goers should set up their blankets on the National Mall between 4th and 7th street. The movie will go on rain or shine, but will be called off if there is lightning.
This is the 17th year of the festival. Earlier this summer, the festival screened "North by Northwest," "The Poseidon Adventure" and "Desk Set."
