Timothy Olyphant and Mary Elizabeth Winstead have joined the cast of the actioneer, Live Free or Die Hard for 20th Century Fox.

Len Wiseman is directing Bruce Willis in the fourth installment of the Die Hard series; the story is of an attack on the U.S. computer infrastructure that begins to shut down the country. The Hollywood Reporter says the mysterious figure behind the scheme has figured out every digital angle but never counts on the old-fashioned, "analog" McClane. Olyphant will play Willis' nemesis, while Winstead will play Willis' daughter; Justin Long and Maggie Q are already part of the cast.

Live Free or Die Hard is currently shooting in Los Angeles; a June 29, 2007 release is scheduled.
