Warner Bros.’ “The Lego Movie” will be the big winner of the President’s Day weekend box office while openings of Sony’s “RoboCop” remake and Warner’s “Winter’s Tale” look disappointing, early forecasts indicate.

“Lego,” with $80 million in its first week, is showing impressive staying power with a Friday projection around $13 million for a 4-day total ranging from $50 million to $60 million. The computer-animated comedy should surpass “Ride Along” as the year’s top grosser by Sunday.

The “RoboCop” reboot, starring Joel Kinnaman, took in $5 million on Wednesday and Thursday and appeared headed for a four-day total in the high teens — well below recent forecasts and a downbeat portent for a film that carries a $100 million price tag with MGM co-financing. The action film, a remake of the 1987 cop hit, has already grossed $40 million from 27 international markets.

Early results were even gloomier for fantasy romancer “Winter’s Tale” with $4 million on Friday and a four-day total in the $11 million range. “Tale,” starring Colin Farrell and Jessica Brown Findlay has a price tag of nearly $60 million.

Sony-Screen Gems’ “About Last Night” was turning in the best performance of the new entries with about $10 million on Friday for a 4-day cume of mid-to-high $20 millions for the ensemble comedy, led by Kevin Hart.

Trackers noted that Friday’s actual numbers could vary significantly from forecasts, citing improved weather and Valentine’s Day falling on a Friday — which led to to far stronger advance sales than usual.

Universal’s “Endless Love” launched respectably with opening-day estimates from $5.6 million to $7 million. “Love,” which only cost $20 million, could finish the four days with nearly that amount already in the bank.

Sony’s “Monuments Men” was showing respectable legs with forecasts for $15 million for the four days. The George Clooney-Matt Damon starrer grossed nearly $29 million in its first week.
