Shoulder pads, Dr. Ruth and “Dynasty” are just a few artifacts from the ’80s unlikely to make a comeback anytime soon. Certain classics, however, will always remain timeless—and E.T.: THE EXTRA-TERRESTRIAL is one of them. Head out to Centennial Olympic Park tonight for an evening of nostalgia with Screen on the Green’s showing of this classic family film. Show up at 7 p.m. to kick back and enjoy the sounds of local pop/rock artist Bria Kam. Admission is free (but don’t bring any glass containers, alcohol, grills or pets, please). 404-575-7888. www.peachtreetv.com.
