>> on actual events that occurred during that period
Good. ? That’s a selling point, a strong element in favor of the story.

>>>but as old as I am I still believe in magic,
But, alas, that’s not the primary factor to consider. The more important one is whether the target audience for the movie will believe in magic.

And, in modern drama the rule of the thumb is that the protagonist should get no lucky breaks, have no lucky magic that enables him to solve problems and win his objective goal. ?He must win success the old fashioned way by hard work, resourcefulness and courage.

There are ?two exceptions to that rule:

1] a protagonist may have a magical gift if and only if the antagonist — his most dangerous adversary — likewise has the same magical gift. ?Example: ?”Star Wars: The New Hope”. ?Luke Skywalker has the gift of the Force. ?And so does Darth Vader. ?And Darth Vader has lots of experience, has had a lot of time to develop his skill. ?Luke Skywalker hasn’t; he’s a beginner in desperate need of a mentor/master to get him ?to the Master level if he is to have any hope of prevailing.

2] The gift comes with a corresponding curse or downside that threatens not only to defeat the protagonist but destroy him or her. ?This is a standard operating “feature” of special gifts or powers in mythology. ?Cassandra is blessed with the gift of ?foretelling the future — and cursed with the fate that nobody will believe her prophesies. ?Midas gets his wish granted so that he can turn everything he touches to gold — which means he is doomed to starve to death because all the food he touches turns to inedible gold.

And in our contemporary super-hero stories, the element kryptonite renders Superman a mere mortal; it takes away his super-human powers.

To give the protagonist a magical power that no one else possesses, ?that has no curse or downside, ?that the protagonist can pull out of the hat like a rabbit whenever he needs it, ?smacks of a “deus ex machina“. ?That is not a ?selling point for a story but a deal killer, a serious liability. ?A “deus ex machina”, magical gimmick makes the solution to the plot problem contrived and it diminishes suspense.

Just saying.

BTW: ?do you have personal experiences lucid dreams?
