In the middle of 2000 - 2010 I saw a TV series about a boy, who after school went to work for an old man at a shop. I don't remember clearly but shop sells old artifacts, books, suchlike.
This boy found a book. He read this book and in it a movie plays, based in an alternative fantasy world. In this world there is a war. I think they used modern guns in the war. Also I remember dragon or something like that.
The alternative world and this boy were connected in some mysterious way.
Maybe someone know about this series?
These series was recorded by live, not animated.
