Each area of Brazil has a slightly different means of celebrating. Though unsaid, there is always a competition as to which city parties hardest. This originated in the 18 century, and the organised competitions are one of the most appealing parts of Carnival, even today.

Unidos de Tijuco is the reigning parade champion, having carried off last year's event with a pastiche of stage delights, including Batman on skis and a Michael Jackson impersonator dancing on a float inhabited by aliens. This year, the school was looking to outdo itself with its long bow to US blockbusters.
Thus the school put its $5 million parade budget to innovative use.
