Projections for the superhero film keep being revised upward by major tracking services.

The forecast keeps getting better and better for Disney and Marvel Studios' Black Panther, which opens Friday in North America. Hollywood's leading tracking service NRG on Monday revised its opening weekend estimate to $165 million or more for the four-day Presidents Day weekend — which if it holds would be the top February launch of all time — according to sources with access to tracking. When Black Panther first came on tracking two weeks ago, NRG forecast a domestic opening of $125 million. By last week, that number had shot up to $150 million-plus.

Directed by Ryan Coogler, Black Panther is unprecedented in being a big-budget studio tentpole featuring a virtually all-black cast. In the film, Chadwick Boseman stars as T'Challa/Black Panther alongside Lupita Nyong'o, Michael B. Jordan, Daniel Kaluuya, Letitia Wright, Winston Duke, Angela Bassett, Forest Whitaker and Andy Serkis. If NRG is right, Black Panther could potentially notch one of the top five or six domestic openings ever for a superhero film, not accounting for inflation. Of course, tracking often misses the mark. Either way, the pic appears headed for greatness in North America. The big unknown is how Black Panther will fare overseas, where Hollywood films with a black cast are perceived to face challenges. Disney insiders expect Black Panther to open in the $75 millionto $115 million range. The tentpole rolls out in about 70 percent of the international marketplace this week; major territories where it doesn't open until later include Russia (Feb. 22), Japan (March 1) and China (March 9).
