But at the Cannes Film Festival today there was proof that anything is possible in the movies as it was transformed into a winter wonderland for Jim Carrey's new flick, A Christmas Carol.
The actor and fellow cast members, including Colin Firth, rolled up for a photocall where they quickly set about having fun.

Arriving in style by horse-drawn cart, the American actor picked up clumps of the pretend snow before throwing it around.
And it was certainly a strange sight to behold as flakes of the (fake) white stuff fell - under the blistering Mediterranean sun on the normally grassy knoll in front of the Carlton Hotel.
In Robert Zemeckis' 3D version of A Christmas Carol, set for release in November, Carrey plays curmudgeonly Ebenezer Scrooge, with Gary Oldman as his clerk and Colin Firth as his nephew.

Disney is engineering a seven-month campaign to get A Christmas Carol positioned for its Christmastime opening, hence the early promotion of the feature.
American actress Robin Wright Penn is also starring in the movie.
It is an animated retelling of Charles Dickens classic novel about Victorian-era miser Scrooge who is taken on a journey of self-redemption, courtesy of several mysterious Christmas apparitions.
