Hi pplz

This movie would have been at least 15-20 years ago

Fantasy/Adventure.. all I can remember is that a boy touch some kind of black stone and it takes him to another world that has drawf, witches, horse-men, trolls and all of those guys

Which all of the different races he meets up.. end up helping him defeat the evil witch at the end of the movie..

At the end of the movie he is sent back to his normal life and his parents find the stone in the oven and touches it and THE END

If you guys can please help get the tittle I been trying to figure out for the past many years it be much appreciated

Sounds vaguely like Time Bandits (1981) (http://www.imdb.com/title/tt0081633/).

Thanks for your reply .

But I'm pretty sure its not that movie

Cheers
