I can’t emember this movie from when I was a kid. Early to mid 90s. All I remember is these two kids were friends. One was I believe a white kid and he had braces. I remember him yelling for some reason and the camera zoomed into his mouth/braces. His friend was I believe a Native American kid who loved rockets. I believe it ended with an adult version of the native American kid shown as an astronaut.
