and no its not tenement...
at the beginning of the movie... there was this young girl playing alone w/ her ball and it rolled away... into the basement (or somewhere dark and creepy)... there was some sort of short ugly creature (possibly a troll??) w/ this magical ring... and with the ring he got her under his spell... yadda yadda yadda (I don't remember the whole thing i was 6 or 7 at the time)... so anyway... the rest of the movie takes place in this "other world" and the portal is in some apartment and this boy ( her neighbor or her brother) ends up looking for her in it... and all i remember is lots of mist and vines and she was in a glass box "asleep"... i hope this is enough information... TIA...
But you were so close!
The movie you are looking for is Troll (http://www.imdb.com/title/tt0092115/), a classic.
If you like that one, I recommend Troll 2 (http://www.imdb.com/title/tt0105643/).
dear god i had a feeling it was troll lol... i'll check it out... thanks!! lol
