“The Dark Knight” is believed to become the summer’s highest-grossing movie as it is heading toward the $200 million mark. According to Variety, the Batman sequel made $24.6 million at the domestic box office Monday and it has made a total of $182.9 million in four days.

Even though distributor Warner Bros. estimated that “The Dark Knight” would fall about 18% on Sunday and other studios said it would fall 20%, the movie slipped only 9%. With this impressive interest from the audience, “The Dark Knight” has many chances to become the summer’s highest-grossing film.

Warner Bros. domestic distribution chief Dan Fellman said that it was very likely that the movie would surpass “Iron Man” ($314.4 million to date) and “Indiana Jones and the Kingdom of the Crystal Skull” ($312.6 million to date).

“I think that's not going to be a difficult task. I think we're going to be way up there,” said Dan Fellman, according to the Los Angeles Times.

Some say that “The Dark Knight” could reach the total of $400 million. The highest-grossing film is “Titanic” with $600.8. “Dark Knight” is played in 4,366 runs and it should earn about $230 million in the first week.

“The Dark Knight” earned Sunday the record sum of $43.6 million. Warner Bros. expects that the movie will win at least one more weekend and earn many millions this week.
