Liam Neeson stars in “The Grey.” Neeson's survivalist thriller topped the box office this weekend with $20 million.

NEW YORK — Beware the Liam in Winter.

Liam Neeson’s “The Grey” topped the weekend box office with $20 million, according to studio estimates Sunday, continuing the actor’s success as an action star in the winter months.

The Alaskan survivalist thriller opened above expectations with a performance on par with previous Neeson thrillers “Taken” and “Unknown.” Those films, both January-February releases, opened with $24.7 million and $21.9 million, respectively.

But the R-rated “The Grey,” which has received good reviews, drove home the strong appeal of Neeson, action star. It’s an unlikely turn for the 59-year-old Neeson, previously better known for his dramatic performances, like those in “Schindler’s List” and “Kinsey.”

“Liam is a true movie star, period,” said Tom Ortenberg, CEO of Open Road Films. It’s the second release for the newly formed distributor, created by theater chains AMC and Regal.
