I remember these movies there was also one called "Glitterball" it was about a small ball that came from space and this boy found it in his garage.As for Sammys super T-shirt i used to have this movie on tape.i remember i taped it from BBC.But when we moved house the tape got lost,i have tried now for the last 5 years to try & get a copy but i have had no luck.I have even tried ebay & contacting the BBC direct.The only movie i have from The Childrens Film Foundation is a movie called "Tightrope To Terror"
