Hear a baby crying in a stroller in NYC? May want to let that pass. Could be a devil baby that contorts itself and pukes. In this particular case, it may be a robot designed by the folks at Thinkmodo for another horror film promotion (remember the Carrie telekinetic prank in a NYC coffee shop?). This one is to promote “Devil’s Due,” and in about 24 hours it’s past 15 million views (1/16 update: 26 million views in 2 days). That, friends, is viral.

It’s “Devil Baby Attack” and it’s taking YouTube by storm. I’m probably most impressed by the way I learned about this. On a phone call with my mom this evening. I guess I’ll have to call her more often.

Some feedback/thoughts:

• The prank is beautifully executed from beginning to end. We’re shocked. Then we see behind-scenes. No wasted shot.
• Excellent job on “seeding” it. There’s no way it would have been seen this many times — so quickly — without a smart promotion of the clip itself (bloggers, journalists, etc).
• Given the 22K comments, I’d say the majority of the views are real views. When videos are “gamed,” you see a really low number of comments. Rough math: 22K comments divided by 15 million views is .0015 percent of viewers commented. With more programatic  stuff, you see a slightly better ratio. For instance a recent RWJ video got 200K views and 1,700 comments (.0085 percent).
• I would love to see a bit more of the off camera laughs and the team behind it — It helps when the viewer has a chance to connect more with the creators. But it’s a horror film promo so I suppose you have to keep it somewhat dark and mysterious.
• I’m glad we’re no longer concerned about making these appear non sponsored. The video’s end reveals it’s a promo. And if you’re gonna have a logo at the end, there’s no shame in providing a link to the movie site for Devil’s Due (www.devilsduemovie.com). This would drive traffic to the film site’s real trailers and almost invariably help convert more of these 15 million views into ticket-paying customers. Even better: give us a reason to hit the horror site. As long at the viral stunt is this good, we’ll forgive the plug at the end.

Finally, a note to Thinkmodo team: for the love of God people, I missed my invite to these productions. I’ll consult for free to see you guys pull the next one off. I’m one of YouTube’s most-viewed pranksters, an author of a book on viral video marketing, an advertising executive and a horror fan. And I can keep a secret. What else do you need?
