I love Dragons. I do not find them scary but I believe they are wise.
In Tv series Merlin there was this huge Dragon (voice by John Hurt)
He also narrated in BBC documentaries like Human Planet. I think he is equivalent of either Tuncer Kurtiz who narrated Turkish version of BBC Life or Haluk Bilginer who voice acted in Cosmos.
Similarly the voice of Smaug (the Dragon in the Hobbit) is impressive. Benedict Cumberbatch was the voice actor for Smaug.
