Valentine’s Day and President’s Day should pack a sizable punch at the weekend box office, though East Coast blizzards could cut into the holiday fun. Sony-Screen Gems’ “About Last Night,” which is tracking in the mid-to-high $20 millions in four days, should top the weekend’s four new wide entries.

Still, Warner Bros.’ hit holdover “The Lego Movie” is expected to win the weekend, with a potential $50 million four-day gross.

Among the pics looking to attract couples on Valentine’s day, a pair of PG-13-rated entries — Warner’s “Winter’s Tale” and Universal’s “Endless Love” —  join R-rated “About Last Night,” with the former two each expected to gross in the mid-teens through Monday.

Comedian Kevin Hart will end up competing with himself, appearing in both “About Last Night” and Universal’s $100 million-plus grosser “Ride Along” in its fifth frame.

Sony’s other wide release, “RoboCop,” which bowed with $2.8 million on Wednesday receiving a solid ‘B+’ CinemaScore, should land somewhere in the mid-to-high $30 millions in six days. The action remake of the 1987 original already has grossed approximately $40 million from 27 international markets. Pic expands this weekend to countries including Mexico, Russia, South Korea and Spain.

FILM REVIEW: “RoboCop” Is Smarter Than You Think

Elsewhere internationally, Warner’s “Lego Movie” broadens to the U.K., after grossing $18.7 million last weekend in 34 day-and-date territories, of which the biggest contributors were in Latin America.

Stateside, “Lego Movie” is likely to drop between 35% and 40%, putting it in the $40 million range Friday-Sunday. The toon should see a hearty President’s Day gross, adding around $10 million from kids out of school. “Lego Movie” has grossed just shy of $78 million in its first six days domestically. The film is expected to cross $100 million by Friday.

The weekend’s diverse lineup should keep totals ahead of this time last year, when Fox’s “A Good Day to Die Hard” topped the long holiday weekend with $28.6 million.

Theater traffic on Valentine’s day should account for roughly 35% of the weekend gross for pics like “Endless Love” and “Winter’s Tale,” especially since the harsh winter weather on the East Coast should have dissipated by Friday.

“Endless Love,” which cost around $20 million to produce, stars Alex Pettyfer and Gabriella Wilde as the opposite-side-of-the-tracks lovers from the original film from 1981.

“Winter’s Tale,” meanwhile, which toplines Colin Farrell and “Downton Abbey’s” Jessica Brown Findlay, tells a time-skipping story of reincarnated lovers from different centuries. The film, from writer-director Akiva Goldsman, carries a more hefty price tag, costing just less than $60 million to produce.

And with a little more than two weeks left until the Oscars, the Weinstein Co. is expanding best picture nominee “Philomena” to 1,225 domestic locations, up from 504. In about three months, the film has cumed nearly $30 million Stateside.
