The blog website "/Film" noted in July 2014 with the release of hand-drawn concept art for "Frozen" (which grossed over US$1 billion worldwide), that any future hand-drawn animated films have been "killed" for the time being due to "The Princess and the Frog" failing "to ignite the box office". Two months later, however, many Disney artists announced they were working on a new independent hand-drawn animated film, "Hullabaloo", as part of an attempt to bring back hand-drawn animation, consisting in three short films, while others got later involved on making the Netflix animated film "Klaus", released in 2019.
