The part of the goat (played by Agnes) was written so that she stands still the entire film, but every time we called action she walked away.
The film was shot in May and June of 2008 so production moved 30 tons of snow to create the winter scenes. The majority of real snow was shavings from local ice rinks.
Tx6, which is billed as 'two tons of granite' is actually made of foam and weighs about thirty pounds.
