alone version, Baltar is  executed halfway through. This version was actually released theatrically  first in Canada before the TV version aired in the USA.  It was eventually  released to theatres worldwide (including the U.S.). When it became apparent  that the series would in fact be made, an alternate ending and version of  Baltars execution scene was filmed.  In the Series version, Baltar is "held  for public execution" instead of being beheaded at once.  When the Cylon  "Imperious Leader" who ordered his execution is killed in the explosion of  the planet Carrillon, his successor orders Baltars release so Baltar can  command the Cylon Base Star that will chase the human refugees throughout the  series.  All this information is given in an "Epilogue" tacked on at the end  of the film.
