It's SOP for a protagonist to resist the "Call to Adventure" entailed the inciting incident, for him to be a reluctant protagonist. ?In fact, it makes for a stronger character arc if he initially rejects the call.
Even so, there has to be a credible reason, an incentive, a compelling event for overcoming his reluctance and pushing him across the thresh hold and on the journey.
Recall that in ?"Star Wars: A New Hope", Luke Skywalker rejects Obi-wan's call to join the rebellion. ?His excuse is his uncle & aunt; they are depending upon him, he's got to get back to his chores on the farm. ?But when they are killed by soldiers from the Empire, that excuse is removed. More than that, he's motivated: ?family blood that's been shed. ?Luke now has skin in the game.
Re: the setup for "Lord of the Rings": ?Bilbo is given the ring , sent on his journey ?without ?(IMHO) acquiring any compelling skin in the game. Except his "Call" comes after a prologue that dramatizes the importance of the ring to the audience. ?So even if Bilbo initially doesn't have skin in the game, doesn't appreciate the full significance of the ring, ?the audience has been tipped off.
Also, ?"The Lord of the Rings: The Fellowship of the Ring" had an advantage Lucas's story didn't have -- and neither does yours. To wit, the saga ?had already been pre-sold, test marketed for movies, if you will, ?as a very popular book trilogy. ? The general story had a large and dedicated following eager to see the?saga made into a movie.
IMHO: I think the way George Lucas incited his protagonist's journey is superior, a better model to consider. ? Because, to repeat, your script like Lucas's 1st Star Wars script doesn't have that built-in advantage of a pre-sold audience familiar with the characters and story.
One final thought: ?think franchise. ?Because that is what ?movie makers are looking for in original scifi/fantasy stories, that they ?have potential to become origin stories ?for sequels. Can you frame your story so that while it solves the immediate dramatic problem, it leaves the door ajar for sequels? Is the world in our story ?capacious enough to hold further adventures for your protagonist?
Regards and best wishes with your story
