Wiseman, according to TheWrap, is currently in negotiations with 20th Century Fox direct the film. He will also be producing the film alongside Lorenzo di Bonaventura.
Die Hard 6 is expected to act as a prequel of sorts to the franchise. It will apparently be set in 1979 in New York and focus on a youthful John McClane. Bruce Willis doesn’t have a deal locked down just yet, but he’s expected to return for present day sequences.
Last year, it was rumoured that Samuel L. Jackson's Zeus would also make an appearance. But nothing has been confirmed just yet. A prequel with modern day sequences would allow plenty of scope for appearances from the Die Hard franchise at large.
Expect more news from Die Hard 6 in the near future.
