Back in the late 90s or early 00's, I saw this movie about some kids that were being put down by bullies. I think that a soccer ball falls out of nowhere or somehow they find this ball that has life. If not mistaken it can fly or float, and the place where you can inflate it is like the eye or the lens where it can see.
I believe it is European, French, German, UK... Because of the buildings and it was a bit gloomy. Had that grey color of cold weather. The name of the kids also seemed a bit weird. I think the kids try to help the ball. I don't recall what language it was. This is a movie from the late 80s ,90s or early 00s. I don't recall much but it was the size of a ball, saw it once on TV. I want to really say it was a soccer ball.
