THE STORY ABOUT THE ACTORS BEHIND DEREK SMALLS, NIGEL TUFNEL AND DAVID ST. HUBBINS SUING THE OWNER OF THEIR CREATION IS REPRESENTATIVE OF A REPUTEDLY COMMON PROBLEM IN THE ENTERTAINMENT BUSINESS

The problem is that creators are allegedly routinely shortchanged on their cut of the income from their creations.  According to the accounts I have read, sometimes they are shortchanged by creative accounting, and other times by outright lying about sales volume.  
You do remember the characters referred to in the title to this post, right?
Did you know that Harry Shearer, who played Derek Smalls, is also a voice actor on The Simpsons?
