Richard Gere's high profile is luring renters to his cop drama "Internal Affairs." In two weeks, it rocketed to No. 4 on the Billboard magazine chart. Though it earned a respectable $27 million in theaters, "Affairs" has the rental market appeal of a movie that grossed two or three times as much. "Family Business" didn't do nearly as much box-office business as expected when it came out last Christmas. Considering its high-powered cast--Dustin Hoffman, Sean Connery, Matthew Broderick--and respected director, Sidney Lumet, its $12-million box-office gross is rather puny. But its star power is beginning to dazzle renters. "Business" started slowly in the rental market, but jumped 10 places to No. 9 in its third week on the chart. "We're No Angels" is no big rental hit. After peaking at No. 13, this newcomer is already sliding down the chart--to No. 17.
