Twitter‘s new Vine app has buzz in the microblogging platform since being introduced in January. Now FilmDistrict is using the looping video tool to promote their March 22 actioner Olympus Has Fallen. Oscilloscope led the way last month by cheekily announcing they were releasing their indie It’s A Disaster in 6-second chunks on the app: “It was so clear to us that six-second loops of videoOlympus Has Fallen Vine, edited in-phone, and posted in real time was and will be the future of film distribution”, quipped a studio press release. FilmDistrict’s approach is more straightforward. Fans are encouraged to upload ’6-Second Video Review’ of the Gerard Butler-starrer to Vine which are then culled online at Olympus6SecReviews.com. With the White House action-thriller hitting theaters this week, the distributor’s been folding nontraditional marketing methods into its campaign, including a sponsorship of Break Media’s new Armed Response action webseries. Social media’s impact on moviegoing was the talk of 2012′s CinemaCon, and that was before users were tinkering with and sharing 6-second videos on their iPhones.
