For those of you who think BB or ED was too short:
Do the math:
Comparing: BBB to Shrek 4
Shrek 4 BBB
Team: 60+ Team: About 6
Time: Over 1 h Time: 8 min
Production Time: 4 years Production Time: 6 months
So, if there were 60+ Blenderartists of BBB Team Quality, we could make movies that woud last a lifetime.
