‘Impact’ holding steady

Grossed over $3 mil Monday

“Deep Impact” continues to do sizable damage at the box office, following its stunning $41.2 million weekend debut.

The Paramount/DreamWorks co-production grossed slightly more than $3 million Monday and $2.75 million Tuesday. The solid numbers bode well for the disaster pic’s second-weekend prospects.

Paramount execs are expecting a moderate drop of between 35% and 40% for the three-day frame beginning May 15. Buena Vista’s “The Horse Whisperer” and WB’s “The Quest for Camelot” debut that day.

Competition will get considerably steeper on May 19, when Sony’s “Godzilla” enters the fray.

The midweek numbers are somewhat unusual for North America. Typically, films do slightly better Tuesday than Monday because Canadian theaters offer steep discounts on Tuesday.

However, Tuesday night’s NBA playoff games may have had an adverse effect on movie attendance among men. Other male-oriented films, including “Woo” and “He Got Game,” also saw drops, while WB’s romancer “City of Angels” was up Tuesday.

While it’s difficult to assess a film’s long-term prospects before its second weekend in release, “Deep Impact” now appears on course to gross between $115 million and $150 million in North American theaters.
