Each year preparations are made according to a chosen theme.

This year's chosen theme doesn't help to narrow the options.

The festival screens about 15 movies, chosen both for their box office success, and for their appropriateness to each year's chosen theme.

Yearly, its activities vary depending upon the chosen theme for the year.

Carnival floats can be very large and comprise a number of characters, props and scenic elements all organized around a chosen theme.
