What happens when you put a ton of popular YouTube stars on a set and get the cameras rolling? Dirty 30, that’s what. Released to adoring fans in September in theaters and digitally, the movie stars YouTube’s “Holy Trinity” of Hannah Hart, Mamrie Hart (who wrote the screenplay), and Grace Helbig. It also features dozens of other internet phenoms, like Anna Akana, Drew Monson, Flula Borg, Rhett & Link, and Timothy DeLaGhetto. The film hilariously tells the story of thirtieth birthday party gone wrong, and its YouTube channel is filled with behind-the-scenes clips and comical collaborations between the leads and their internet friends.
