updated: In a world of high fantasy, four archetypical adventurers have a brush with death only to learn their fates are determined by a ?role playing game?; they journey into our world, where the laws they know no longer apply, to meet the godlike beings who control them (comedy).

The ";" that separates the two sentences stands like a hole in the script to me. Again, you should focus on the movie structure and you will find a way to write a one sentence logline where all the elements are connected, with clear stakes and goals.

With a touch of irony you can almost avoid to specify that it's a comedy.

Look at the Galaxy Quest logline to get inspired :
"The alumni cast of a space opera television series have to play their roles as the real thing when an alien race needs their help" (imdb).

"Confront" is vague and rather static. So they meet their controllers face to face. Then what do they do? What must they do? What becomes their objective goal?

"high fantasy": ok I didn't know this expression, then it's perfect.

This has a good hook. It might need an MC.

I assume that Earth is the destination of their journey. Do we identify with the traveler's or with the game players? I also assume that freedom is the goal (if we identify with travelers) and defense from invaders is the goal (if we identify with game players).

Kind of reminds me of Galaxy Quest - where reality meets fantasy.

The term 'high fantasy' means a 'lord of the rings' type fantasy world. Elves, wizards, swords, magic. Sword a Sorcery would also work.

Yeah, I think the word 'must' is confusing.
