In June 25, 2011 Sony Pictures Entertainment and Sony Pictures Animation  in anticipation of the release of The Smurfs® organized these worldwide events. Fans in 11 cities around the world set a new Guinness World Records title for the Largest Gathering of People Dressed as Smurfs within a 24-hour Period in Multiple Venues.

As worldwide audiences turned out to celebrate the birthday of Peyo, the creator of the Smurfs, fans came to events dressed as Smurfs (white Smurf hat, white pants and shoes, and body painted blue). Adjudicators from Guinness World Records confirmed that a total of 4,891 people dressed as Smurfs in 11 locations simultaneously around the world, claiming a new title for Largest Gathering of People Dressed as Smurfs within a 24-hour Period in Multiple Venues.

The global record was set by people dressed as Smurfs in Brussels, Belgium; Athens, Greece; Scheveningen (The Hague), Holland; Dublin, Ireland; Mexico City, Mexico; Panama City, Panama; Warsaw, Poland; Moscow, Russia; Johannesburg, South Africa; New York, USA; and London, UK.

It was a hot June day at Athens with the temperature reaching 38 Celsius starting from 15:00 until 20:00. Right after the event, the photos were uploaded to a microsite built especially for the events.
