There was a fantasy movie on television in the early 70’s which may or may not have been in theaters. The plot is of a young man in search of a place where people lived “happily ever after,” which I believe was to mean that they became immortal. He finds the place early in the movie, but is given a set of tasks he must accomplish before he will be allowed to come inside. I believe the tasks were to find artifacts like a heart of gold and a feather of truth, or something like that. I also recall the antagonist was living in the town and tried tricking the hero several times. The special effects were B-rate 1960’s, but I remember really loving the movie as a kid. Might have been a Eurppean movie that was dubbed. Any thoughts would be helpful, thanks!
