According to IESB, Zak Penn has been given the sole writing credit for The Incredible Hulk, despite the fact that Edward Norton re-wrote his draft. It is well known that one of the only reasons Norton agreed to do Hulk were if he had creative input, in this case re-writing the script.
The IESB contacted Zak Penn’s office to ask about the credit. They confirmed Penn will be receiving sole writing credit on the film.
Universal reps are saying, “WGA determined the writing credit not Zak or Edward or Universal or Marvel. WGA always determines final writing credit for our films right before the film comes out. Up until that time, we include the writers on the project to date.”
A call to the WGA got this response, “Zak Penn is receiving sole credit for story and screenplay.”
Apparently, there was arbitration, which is quite common since two screenwriters were listed. The WGA sided with Zak Penn.
In my opinion it wouldn’t be hard just to give them both credit. I’m not a WGA script expert but it would seem the logical and fair thing to do. It’s not as though the script had input from many writers such as Catwoman (14+ writers in total). In cases where there are lots of writers then I suppose this process of choosing is better, but when only two writers have worked on the script it would see, fair to credit both.
If everyone from the catering ladies to the lighting guys get credited than surely one of the writers should get credit somewhere.
