for me: a film called "the spaceman and king arthur". Later released as Unidentified Flying Oddball
features an astronaut whose space mission ends up with him being transported back in time and landing in the court of King Arthur. co-starring the guy who played Sgt. Wilson in Dad's Army.
Did anyone else ever see this? I know this thread could turn a bit "remember white dog poo?" but just wondering if you have memories of films you watched / books you read as children which, if it were not for the internet, you'd swear were a figment of your imagination.
