In 2009, Europe was witness to an incredibly ingenious marketing act.
Disney, to promote their 2009 release Up in Europe, worked together with a well-known balloon marketing company to make a genuine balloon with an undercarriage that looks precisely like your house in the movie .
The entire construction of the balloon itself can be treated as an engineering genius, and it took control of 6 months to finish! The greatest surprise was the one Disney had prepared for their London promos- they flew the balloon right under the Tower Bridge! The act was much discussed and reported in international media.
