What's the name of this 70s-80's fantasy movie?!

I remember watching it when I was growing up in the 80's and early 90s!. I only remember bits and pieces but here they are!.

Its a fantasy movie that involves a boy who gets transported into another dimension!. A fantasy type world where they fight with swords and have castles, etc!.

I remember him walking at night in the present day and watching a woman beat the dirt out of rugs!.

When he get's transported to the other dimension the most prominant things I remember is that

a) he get's an invisibility cloak
b) I remember something about a well
c) He goes into a cave and i think there is a man in there who makes swords!. This kid pulls out a sword with a pretty elegant golden hilt!. This sword is special because it can cut through stone and the villian of the movie has a stone heart!. The kid uses the sword to cut through a big chunk of stone while he's in the "cave"
d) the villian of the movie has a stone heart
e)the kid eventually makes it to his castle and gets in a fight with him and stabs him in the heart with the sword
f) something about a yellow canary flying out a window or something at the end

Thanks for your help guys! I've been trying to figure it out for awhile and have stumped all my movie buff friends :)Www@Enter-QA@Com
