Please try and answer this. When i was younger, i remembering watchin a movie. It was about a brother and a sister, they were young and it was cartoonized. I remenber them walking along a canal or somthing at the start. There was somthink about a profeser in it who helped them get home because they where lost. I think in the end it was a dream. PLease help, its important to me because the brother was older then the sister and he looked out for her like my brother used to do for me.
Thanks

Pleaseeee Helppp
