well, the very low budget movies that i worked on in Thailand had almost zero stars in it except for one where Maggie Q was in it... and she isn't really that big of a name is she?   I did get to meet McG during that film though and I have lines in it, so if it is ever released my name has to be in the credits.  woo hoo!

However, prior to that i was an extra in a string of really bad films one of which where i was a part of an elite group of "giant insect hunters" called "Thorax"... our leader was Luke Duke from the Dukes of Hazzard.  His name is Tom Wopat and i was a bit starstruck because I was such a fan of the TV show in the 80's.  

He was surprisingly down to earth and pretty ok with the fact that the movie was shit.   Whatever right?  He's still getting paid.  

Anyway, the point is that these films that i had minor roles in involved HUNDREDS of crew members and we would do the same scenes dozens of times.  Assuming that everyone there has to be paid, including the lion's share going to the main cast and director, i can't imagine how thin the budget must have been spread on 100k.
