It is hard to believe that “The Dark Knight” will really manage to sink “Titanic.” Although the latter faces tough competition from the Batman movie, the Christopher Nolan-directed production will remain on the second spot with approximately $510 million to $520 million, Warner Bros. Pictures expects, as reported by Reuters.

In addition to this, “The Dark Knight’s” winnings are far from surpassing “Titanic’s” (1997) remarkable $601 million

The unbeatable popularity of James Cameron’s film may be payable to Leonardo DiCaprio’s fame among teenage girls who went to see the movie over and over again, helping the well-known blockbuster earn $1.8 billion worldwide.

Nevertheless, more than a decade later, “The Dark Knight” went sky-high to an impressive $441.6 million domestically and $263.5 million overseas in only four weekends from its big-screen debut. Since it smashed so many records, the Batman sequel was instantly believed to sail even further than “Titanic” did.

Nowadays major releases record tremendous sums in their first couple of weekends. For instance, “The Dark Knight” brought in $313.8 million domestically in only 10 days from its theatrical release. However, older productions kept on luring audiences even after several weeks. So here we are. “The Dark Knight’s” big-screen popularity may soon come to an end because of its upcoming home video release.

According to Reuters, informed sources said a December release is very likely to coincide with the profitable holiday gift-giving season. Furthermore, this is one of the main reasons why the film starring Christian Bale and the late Heath Ledger is not expected to fill the almost $160 million gap which stands between the first two spots of the biggest movies of all times.
