Northern Comfort: Northern Comfort is a 2010 American improvisational film starring Rod Webber and Greta Gerwig.

" The Boston Globe"’s Ty Burr called it "DIY Dogme dedicated to Webber’s guiding maxim: 'The movie already exists, it’s just waiting to be found.’"  During an interview for Gerwig's Greenberg starring Ben Stiller (Gerwig's first mainstream movie) she was asked whether she'd be doing more films for $3000 and replied, "[Laughs] Maybe not $3,000 budgets but maybe $50,000 budgets.  I'm interested in making low-budget films not for the sake of making low-budget films but because a lot of filmmakers that I want to work with and that I like are working on a smaller scale."
