One Wish Too Many

Wow it's interesting reading all these memories of everyone albeit the last one in 2013 (hoping all are still well). I saw this movie whilst in my latter years at junior school around '78-'80 sat on the cold assembly floor in my school shorts with my legs crossed, but remember how 'magical' the film was! I recall snippets of the film how the young lad could use the powers of the 'magic marble' but yes my biggest memory is that of the steam roller at the end and what happened to the marble after! So here I am in different times led in bed with covid 19 (thankfully feeling not too bad) wondering what I could watch and this film sprang to mind! Finally found it on you tube, writing this as I've watched the first 10 minutes or so and it's amazing how quick the memories come flooding back, so here we are 43 odd years later......'I wish' I can now watch the rest of the film! Lol.
