The 2003 miniseries Battlestar Galactica shared a special effect company with Joss Whedon's prematurely-cancelled cult favorite, Firefly. This enabled the crew of The Serenity to keep flying through the skies of the Twelve Colonies! If you look carefully at the sky sixteen minutes into the Battlestar Galactica pilot, you can see The Serenity on the left-hand side of the screen. A relevant screenshot from Battlestar Galactica is pictured above, and an image of The Serenity, for comparison purposes, below.
