The differences in the 1981 crawl. Star Wars fades out faster and is completely gone before Episode IV appears at the bottom of the screen. The starfield is unique. It is the same basic starfield as TESB, but only is about 80% the same. TESB shows more to the right, the 1981 crawl shows more to the left so you can’t just lift the TESB starfield and have it be accurate. After it pans down, the moons are in slightly different positions and the Star Destroyer has been better composited to remove the heavy black line you can see as it crosses the larger moon in the 1977 crawl. The 1997 crawl returns to some of the elements of the 1977 crawl, such as the starfield and the moon positions and Star Wars not fading out completely until after the crawl starts. The 1997 crawl kept the recomposited Star destroyer.
