Question: What film in the HTTYD franchise was written and directed by Dean DeBlois?

Go Quiet is a music film directed by Dean DeBlois, featuring acoustic renditions of all nine songs from the 2010 album "Go" by Jón Þór (Jónsi) Birgisson.  The film was created as a counterpart to the lavishly produced studio tracks of "Go", with an emphasis on stripped-down intimacy.

He avoids cleaning up and instead procrastinates by playing songs that reflect the night before, the bittersweetness of new year, and the melancholy of a year gone by". <SEP>  It is the sequel to the 2010 computer-animated film "How to Train Your Dragon" and the second in the trilogy.
