Maybe someone can help me here... animated movie, it was aired on the local TV (which had access to elusive European and Asian animated movies) many times when I was a kid.
I strictly remember the climax and the last scene:
>The climax takes place in an old building (I think an ancient ruin, like the Colosseum, or maybe an old mansion) with evil businessmen trying to torn it down with heavy machinery.
>A big fire starts, and the evil businessmen run away, except for the main one, who is a lanky old man (which my memory remembers as a cross between Claude Frollo and Professor Screweyes) riding an excavator.
>He is surrounded by the fire, but remains inside the vehicle, and the excavator turns (or is seen from the kid protagonists' POV) as a monster that roars and struggles, until it falls down taking the evil businessman in it.
>In the last scene, the kids watch as their allies, a group of magicians (who I remember seeing and thinking they are the Three Wise Men), take off and fly making a glittering dust that fall from the sky that could have been snow.
Yes, this entire thing could have taken place on Christmas, for all I know... but I don't remember it being aired around that season in particular. It might be an European animation, or even a Japanese one, but I honestly don't remember enough details to be sure.
