When the Towson Commons opens in the spring, it will include an eight-screen cinema complex, thanks to General Cinema, the corporation that owns the Perring Plaza Cinemas and the York Road Cinemas.
When the Commons cineplex opens, however, the Perring Plazas will disappear. They will be replaced by an economy food mart.
The General Cinema Corp. is apparently not planning to shut down the York Road Cinemas, at present.
''Race the Wind,'' a 39-minute film on the history of sailing, will replace The Rolling Stones movie at the Imax Theater at the Maryland Science Center on Dec. 13. ''Race the Wind'' will continue there through May 8. The film includes sail footage from 1929 to the present.
