for me: a film called "the spaceman and king arthur". Later released as Unidentified Flying Oddball

http://www.imdb.com/title/tt0080062/

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.
