Author Existence Failure: Jerry Russell, who voices Lamies in the English version of Shakugan no Shana (Funimation dub), died on September 5, 2013 following serious complications from surgery in Texas.
No Export for You: The novels. Viz owns the rights to release them in English. Viz released the first two novels in English, then lost interest (even though they're still releasing the manga). No-one else can release the novels while Viz own the English rights, whether they use them or not. Damn.
Even the Japanese cast was subject to this. In the Drama CD that was released in 2004, Shana was voiced by Yui Horie, Yuji Sakai was voiced Masakazu Morita, Alastor was voiced by Akio Ohtsuka, Kazumi Yoshida was voiced by Akemi Sato, Chigusa Sakai was voiced by Yuko Minaguchi, Friagne was voiced by Masaya Matsukaze, Nina was voiced by Masumi Asanonote She would voice Yukari Hirai in the anime adaptaion, and Hayato Ike was voiced by Takayuki Sasada.
