Skip Woods is in final negotiations to write the script for the new Die Hard film for 20th Century Fox.
Woods is known for writing video game adaptation
Hitman,
X-Men Origins: Wolverine and the upcoming
The A-Team.
Live Free Or Die Hard earned $378 million worldwide in 2007 so it's no suprise that sequel is being made. There is still no official story line, but Bruce Willis in one of the interviews said that they will probably go worldwide with the character. Stay tuned for the updates!
Also, there is a comic book prequel to the first film called
Die Hard: Year One.
