Faux Snow for "A Christmas Carol"
Disney tapped Jim Carrey for a new version of “A Christmas Carol” in 2009 — and decided to bring the holiday spirit to Cannes by covering the Croisette with snow.

Shout out to Robin Wright and Colin Firth in the background for looking horrified at the faux snowball fight.

Jerry Seinfeld Flies In to Promote "Bee Movie"
In 2007, Jerry Seinfeld took Cannes by air to promote his big animated push for Disney, for which he served as writer and star and recruited pals like Chris Rock. His giant bee costume might have been worse than his notorious “Seinfeld” puffy shirt.

He was praised for depicting the joyous and fervent act and staying mostly out of the realm of straight-up pornography. Promoting the film, however, was a different story. Producers wallpapered Cannes in posters of a saliva-covered triple kiss and an NSFW image of a penis and a woman's breast after climax.

Howard Stern and His "Private Parts"
