I was trying to express to my friend how cool the movie Mary and Max looked, even though I've yet to see a proper trailer. I don't know much about the movie other than what was listed in the Sundance Press Kit, but I'm impressed by visual direction and the seemingly mature content. The character design ain't to shabby either. From the kit:

MARY & MAX is a claymated feature film from the creators of the Academy Award winning short animation HARVIE KRUMPET. It is a simple tale of pen-friendship between two very different people; Mary Dinkle, a chubby lonely eight year old girl living in the suburbs of Melbourne, and Max Horovitz, a 44 year old, severely obese, Jewish man with Aspergers Syndrome living in the chaos of New York. Spanning 20 years and 2 continents, Mary and Max's friendship survives much more than the average diet of life's ups and downs. Like Harvie Krumpet, MARY AND MAX is innocent but not naïve, as it takes us on a journey that explores friendship, autism, taxidermy, psychiatry, alcoholism, where babies come from, obesity, kleptomania, sexual difference, trust, copulating dogs, religious difference, agoraphobia and much much more.

It slated to open on April 9 2009. Also, be sure to check out its website to see the rest of the characters.

EDIT: I just found the trailer thanks to Slashfilm.
