According to 2K Marin's creative director Jordan Thomas, the setting is "one of the characters we don't want to let go." Thomas added that he thinks Rapture is still "fertile" for as much exploration as the team sees fit.

"I absolutely believe that there might be future games set in Rapture in whatever time period," Thomas said, "but I would also say that I think that the Bioshock brand is big enough that it could evolve." Evolve into more sequels, that is.

"It's more likely that it would be released coincident with BioShock 3 - that also remains to be seen," he added. Looks like we can expect a BioShock trilogy, at least.

An analyst also asked Zelnick whether Take-Two has any creative control over the film. Sticking strictly to financial terms, Zelnick said, "We definitely did structure this deal so that we have no economic exposure or risk... the economic exposure or risk is being borne by... Universal Pictures."

No financial risk would suggest little to no creative control, but he declined to disclose specifics of the agreement.
