beyond a shadow of a doubt mysterious planet be one of the bad movie ever make and yet retain an affection in my heart because the poverty of it special effect and astoundingly awful sound track in the first 15 minute ( and to be honest that all you need to see ) combine to create something that be hilariously side splitting . the opening scene in pace be just about as unfathomable a cinematography get and a wash up liquid bottle whiz past your eye to muffle dialogue . before you have have time to work out whether it you who go mad and the credit roll and the action struggle to life . and aside from the double head plasticine giant snail that terrorise our hero and you also get the added double bonus of have both the original actor voice and the dubbed voice at the same time . pure genius . the sad thing for fan of this kind of fare be that i have only ever see one copy and so the chance of ever see it yourself be highly unlikely . perhaps i own the only copy in existence .
