Famous example I remember is that Joss Whedon pretty much rewrote all the dialog in Speed but never got a writing credit[0] - apparently the rules are written to prevent producers or directors adjusting a few lines to gain a credit, but they don't take into account more substantial contributions. Residuals are also paid to those credited, rather than those who worked as consultants [0] http://www.huffingtonpost.com.au/entry/joss-whedon-speed_n_5473795 http://www.huffingtonpost.com.au/entry/joss-whedon-speed_n_5...
