American audiences awaiting this summer’s crop of super-powered blockbusters might have noticed a disturbing trend: International audiences are seeing select films sooner than we are.Marvel and Disney’s, which officially launched the 2013 summer blockbuster season, had earned more than $300 million in ticket sales before even opening in a single U.S. theater. How? An early release strategy had the coveted sequel conquering Australia, France, Italy, Taiwan, Hong Kong, the UK, Japan, China, Germany and several other nations at least a week ahead of the United States.A similar situation occurs this week with Paramount’s. Thefranchise, by all accounts, is an American-bred product, conceived by Texas native Gene Roddenberry for U.S. television. It’s about as American as sci-fi can get. And yet, it held its world premiere in London, and opened in multiple foreign territories long before it screened for U.S. audiences. That was significant because Abrams – as you know – went to great lengths to protect a valuable secret regarding the identity of the film’s villain. But how do you keep lid on THAT particular can of worms when assorted European and Asian markets have seen the film and are primed to spoil thesecrets on the global Internet?Short answer: You don’t. And so American audiences, in the cases ofand, have had to suffer.But why? The studios claim there is no deliberate strategy in place, with Paramount reps explaining thatopened early overseas because they spotted a window of opportunity with Warner Bros.’ ownmoved around the release-date calendar, creating a convenient hole. (Disney, for the record, declined the opportunity to comment on.)But there has to be more of an explanation than that, and we came up with a few theories after a little digging around about the benefits (and hindrances) of opening a tentpole overseas before launching it in the States.The word we hear over and over when researching this topic is. It long has been a problem for the studios – in the U.S. and abroad – that movies are showing up on illegal piracy sites days or weeks before they are due to land in theaters. Sometimes, as was the case with Fox’s X-Men Origins: Wolverine , the source of the leak comes from within. Other times, its camcorder copies of already opened films that flood international markets. Since studios gross large percentages of their overall take in international markets, it is believed that more studios are trying to open blockbusters in places like China and Japan to extinguish the need to pirated copies.Another key word that pops up while digging isas in the availability of the talent needed to promote these films, and the availability of the press needed to cover just such an event. At a London-based press event for asequel, I was told by a studio rep that UK premieres allow studios to access so many journalists from so many different regions. London has become a very central location for world premieres and subsequent press events."Worldwide release dates often come down to timing issues," Exhibitor Relations Co. Senior Box Office Analyst Jeff Bock told Moviefone in an interview. "When can Robert Downey Jr. trot around the globe? When are the other studios releasing their films overseas, and how can our release maximize profits?”Ah yes, profits. Keep digging, and the final word that surfaces with regard to this story, obviously, is“More than anything else, the shift reflects how the international market, once just gravy for Hollywood, has eclipsed the domestic market as the main source of revenue for mainstream theatrical releases,” Susman wrote in the same Moviefone piece. He makes a good point., for example, has earned $31 million internationally in its first two weeks of release ... putting it well ahead of the pace of Abrams' 2009 franchise reboot. Last year'sis a prime example; it earned $623.4 million in the U.S., but an impressive $888.4 million in overseas territories. And $185.1 million of that international gross was earned in the movie’s opening weekend … before it reached the States.
