Is Battlestar Galactica one of the most beloved TV series of all-time? So say we all!

It's been 15 frakin' years since BSG made its series debut on Syfy on Oct. 18, 2004, and while it would go on to become a cult-and-critic favorite over its four-season run, fans of the original series were less than enthused over creator Ronald D. Moore's reimagining of the series, which first returned as a miniseries in 2003. 

Battlestar Galactica first aired as TV series in 1978 and despite being canceled after just one season, it developed a loyal fanbase, thanks to iconic characters like Apollo and Starbuck. That might be why it took so long for Battlestar to come back, despite multiple attempts before Moore, a Star Trek veteran who is now an executive producer on Outlander, decided to take on the job, even penning a now legendary three-page manifesto that he presented to the network with his pitch for the reboot. 

Titled "Naturalistic Science Fiction, or Taking the Opera out of Space Opera," the document was also sent out to the actors and boldly stated BSG's ultimate goal: : "Our goal is nothing less than the reinvention of the science fiction television series."

And Moore, along with stars Edward James Olmos, Mary McDonnell, Katee Sackhoff, Tricia Helfer, Grace Park, James Callis, Jamie Bamber and more, did just that, BSG going on to win a Peabody Award and the United Nations even hosting a retrospective for the series after it ended its run in 2009. 

To  celebrate Battlestar Galactica's 15th anniversary, we're revealing 15 behind-the-scenes facts you might not know about the show, like which star almost turned down their role, who was "pissed" when they landed a different role than they auditioned for and why Moore almost had objects thrown at him at a fan convention...
