Given the number of bugs that crept in when the video masters for the DC boxset were made, I can believe somebody was drinking in the telecine room and had a little accident!

Nothing was spilled on the film. That shot was made from multiple elements. You had the horizon which was a seperate element and the they comped it into the shot of Luke. When they did that it resulted into the blob.
