Ghost has materialized in video stores and has now been sighted at No. 2 on the rental chart. The romantic thriller, starring Patrick Swayze, Demi Moore, and Whoopi Goldberg, who last week won an Oscar for her performance, seems likely to clean up on video, repeating its success as the biggest-grossing film in 1990. Debuting lower down on the chart is Narrow Margin (No. 32), with Gene Hackman.Half the videos in the top 10 of the sales chart this week are animated, as Here Comes Peter Cottontail hops to No. 9 and two Rocky and Bullwinkle tapes, Mona Moose and Birth of Bullwinkle, return to the top 10.
