Gill has confirmed that The Nolans had direct influence on the script. Goyer might have gotten full credit but Chris and Jonah touched the screenplay. How much? That is unknown at the moment.
It wouldn't be the first time. Goyer wrote the Begins and Knight scripts, but Chris made alterations to both. The final drafts weren't 100% Goyer's, yet Nolan suggested that David was the workhorse and deserved most of the credit.
