PR Newswire reports that DreamWorks and NBC have joined forces in a promotional partnership to produce seven winter sports-themed vignettes starring characters from How To Train Your Dragon. These televised shorts, which began airing on Tuesday, advertised both DreamWorks’ upcoming animated film as well as the 2010 winter Olympics. How To Train Your Dragon hits both traditional and 3-D equipped theaters on March 29th. Thanks to Ryan for the tip!
