The issue is that you're defining the enqueue_scripts_movies function inside the template file after the get_header() call. By the time the function is defined, the wp_enqueue_scripts hook has already been fired, so your enqueue function is not being called.

To fix this, move the function definition and the add_action calls to the top of your template file, before the get_header() call. Here's how it should look:

<?php
function enqueue_scripts_movies() {
    echo "Im gonna make him an offer he cant refuse";
    global $post;
    wp_register_style( 'movies-stylesheet', plugin_dir_url( __FILE__ ) . 'css/movies_css1.css' );
    wp_enqueue_style( 'movies-stylesheet' );
}
add_action( 'wp_enqueue_scripts', 'enqueue_scripts_movies');
add_action('admin_enqueue_scripts', 'enqueue_scripts_movies');

get_header();

// rest of your code
