I'd like to build a list of similar (mostly kid-friendly) movies of a similar sort. Fantasy meets reality...
Labyrinth
The Last Mimzy
Bridge to Terebithia
Zathura
Jumanji
Small Soldiers
Wizard of Oz
The Chronicles of Narnia: The Lion, the Witch and the Wardrobe
What dreams may come
Pans Labyrinth
No Harry Potter or LOTR, thanks.
