A viral mar­keting cam­paign for the summer block­buster movie “Super 8” hit the Web more than a year before its the­atrical release last Friday. We asked senior aca­d­emic spe­cialist Ter­rence Masson, director of the cre­ative indus­tries pro­gram at North­eastern, to ana­lyze the impact of using social net­works to drive audi­ences to the movies.

How impor­tant are viral mar­keting cam­paigns to the suc­cess of summer block­busters, such as “Super 8?” Which other movies have ben­e­fited from viral advertising?

Viral mar­keting, which entails a lot of mar­keting nowa­days, is really crit­ical to the suc­cess of films, whether they are ultra low-​​budget movies or mega block­busters. It grew out of the neces­sity for low-​​budget movies, like the 1999 film, “The Blair Witch Project,” to create an afford­able mar­keting cam­paign. “Blair Witch” was among the first films to hit a home run doing this, and this was way before social net­working and the Internet really caught on. They did it with lim­ited Internet release of infor­ma­tion, as well as books, audio and fake news releases to the media.

The sim­plest form of viral mar­keting is just word-​​of-​​mouth. With “Toy Story 3,” short behind-​​the-​​scenes doc­u­men­taries with the Ken doll and other char­ac­ters were released to get the word out. Two of the most pop­ular angles to take are blasting the social net­works with addi­tional con­tent or using a com­bi­na­tion of dis­in­for­ma­tion and secret clues, which “Blair Witch” started and “Super 8” director J.J. Abrams has taken to the next level.

Social net­working and video-​​sharing sites sat­u­rate the fabric of our cul­ture. In this Web 2.0 world, do film­makers feel pres­sured by movie­goers to create elab­o­rate con­tent beyond that of the film itself to keep audi­ences interested?

Rather than feeling pres­sured, I would say inter­ac­tive media pro­fes­sionals are excited. It’s a whole market rev­enue stream and cre­ative outlet. Abrams really took it to the next level with his TV series, “Lost,” which took full advan­tage of the Internet — with mas­sive amounts of online dis­cus­sion blogs, dis­in­for­ma­tion and back story detail, and its own Wikipedia site.

How do moviemakers keep a film’s details— including plot twists and ending — from leaking onto the Web weeks and months before a movie hits the big screen? In which instances will film­makers inten­tion­ally leak information?

When you don’t want to leak infor­ma­tion, the most suc­cessful example I can think of is “Avatar.” It was the anti-​​viral mar­keting, with total secrecy. How do you do that? It starts early with the first drafts of the scripts. In the past, I’ve received num­bered, coded copies of scripts that are specif­i­cally tagged to me per­son­ally, so if any pages get out, it could be traced to me. They also do this with DVD screeners before Academy Award voting, and before films are released in the­aters. Those are dig­i­tally water­marked, with a highly sophis­ti­cated, secret tech­nology. It’s a really effec­tive deterrent.

These days, leaks are also done on pur­pose for obvious rea­sons — to build hype and get the word out early. People can get so sick of seeing reg­ular trailers, but that tech­nique works as well. Right now, the mass mar­keting cam­paign for “Green Lantern” is over­whelming. This is rare now because of the cost; it’s not done as much out­side of huge blockbusters.
