NEW YORK — The R-rated X-Men spinoff Logan slashed into the weekend box office, opening with a massive $85.3 million that surpassed expectations and ranks among the top March debuts ever.

Hugh Jackman stars in what he says is his final performance as Wolverine. Word of mouth got a boost from good reviews for the unusually dark and dramatic comic-book movie that — like Deadpool — further proves moviegoers' hunger for less conventional superhero films.

Oscar best-picture winner Moonlight had its widest release yet, appearing on 1,564 screens. It turned in its biggest weekend, too, with an estimated $2.5 million.

Last week's No. 1 film, Jordan Peele's horror sensation Get Out, slid remarkably little. It dropped to second place but still grossed $26.1 million.

Final figures are expected Monday.
