That scene where Baltar is arguing with the Imperious Leader about his colony being destroyed against their agreement.Was there scene which shows Baltar being beheaded ?
In the TV version, they get to the centurion drawing his sword, but then he re-sheathes it. The leader says "no, remove him for public execution." The movie version has the cylon draw the sword completely while Baltar yells "no you still need me -aaagghh!" and the camera swish pans away as the swrod reaches his throat. Here are a few versions.
