New Brevoort Formspring

I know you can't comment on film projects, but I hope you can shed light on this. Regardless of bad contracts Marvel might have signed when they were struggling financially, other studios don't have complete carte blanche over your characters, right? Marvel must have some kind of Approval over scripts, so that permanent damage can't be done to your IP? Like Sony couldn't make PETER PARKERLOW: SPIDER-GIGOLO, or Fox make Wolverine a pedophile? Please confirm that there are checks and balances.
