After weeks during which Christmas-season movies dominated the Top 10, the first hits of 1993 are emerging. "National Lampoon's Loaded Weapon 1," starring Emilio Estevez and Samuel L. Jackson, had a strong opening round. Likewise, the Civil War period romance "Sommersby," which bills two of the screen's hottest personalities, Richard Gere and Jodie Foster. The two new films pushed the mega-hit "Aladdin" out of the No. 1 slot.
Also opening, but to unremarkable numbers in fourth place, was the psychological thriller "The Vanishing" with Kiefer Sutherland.
* Still packing in business after 11 weeks in its fairly limited run of 217 screens is "The Crying Game," with a gross of $1.1 million. On 449 screens, "Lorenzo's Oil" managed only $666,000.
