The free movie matinees at the Open Space Visitor Center (6500 Coors NW) continue this Saturday, Aug. 23, with a screening of the computer-animated hit Mr. Peabody & Sherman. The film, based on a segment from animator Jay Ward’s old “Rocky & Bullwinkle Show,” follows a brilliant dog and his adopted boy on a trip through time and space. The film will start at 1:30pm in the visitor center’s media room.
