I'm trying to find te title of a movie I saw when I was a little kid.
It was set in space and also a futuristic theme because of the technology
I think the boy was separated from his father (it was a flashback)
Later in the movie he met a guy who either did something to a ring his father gave him
Or gave him that ring
It was very confusing
There were cartoon aliens in it too
And he also meet a girl
By this time he was probably in his later teens (16?)

Oh and I forgot, he ran away with the girl from the guy who did something to his ring

It could be Titan A.E.

I think so, maybe... do you know where I can watch it? At the starting, the boy/teen was in a space suit and he cut off a piece of rock or something... then he got on a scooter thingy that can fly in space and went to a place (restaurant maybe?) there he meet the guy who did something to his ring. Ty for your help can you tell me where I can watch it? I'll really appreciate that :)

Oh yes, I am sure Titan AE is the movie you are thinking about. You can find it very cheap in any retail store. I have seen it for under $5.00. Or you can buy it or download it from Amazon for a few dollars. I wouldn't try YouTube, it is on there, but its so cut up and poor quality, you'll never see the whole movie.
