George Clooney and teenage vamps, beware — Warner Bros.’ “The Lego Movie” is much bigger than advertised.

Written and directed by Phil Lord and Chris Miller (“Cloudy with a Chance of Meatballs”), the 3D toon is on track to gross $60 million this weekend, making it the biggest box office debut of 2014 and the second-highest February opening of all-time.

The family movie, co-financed by Village Roadshow, is based on the widely popular toy line and riding very strong reviews (97% fresh on Rotten Tomatoes), not to mention premium 3D ticket prices.

WB is so confident in “Lego,” the studio has already commissioned a sequel to the $60 million-produced toon, which is playing in 3,650 locations nationwide.

The voice cast is led by Chris Pratt, Elizabeth Banks, Will Ferrell and Will Arnett.

Adding further firepower to the domestic box office is Sony’s “The Monuments Men,” which may reach $24 million by Sunday, based on early ticket sales.

George Clooney’s World War II drama, co-starring Matt Damon and Cate Blanchett, was originally scheduled to open in December but was delayed this past fall to allow Clooney and the studio further time in post-production.

This weekend’s other wide release, the Weinstein Company’s adaptation of the YA series “Vampire Academy,” should bow to approximately $7 million.
