Cameras prepare to roll on 'Die Hard 4'

Willis in 'Sin City'

The latest film in the Die Hard franchise will begin shooting later this month, with two new cast members joining Bruce Willis.

Variety reports that Justin Long and Maggie Q have been chosen as the co-stars for Live Free or Die Hard, with Underworld's Len Wiseman directing.

Long, 28, has previously appeared in Herbie Fully Loaded and Dodgeball: A True Underdog Story, whilst Asian star Q recently appeared in Mission: Impossible III following a successful spell in the Hong Kong movie scene.

Rumours of a fourth Die Hard film have been in circulation since Die Hard With a Vengeance was released in 1995. Last year, singer Justin Timberlake was strongly mooted as Willis' sidekick.

In a hint towards the nature of the film, director Wiseman has stated: "Our villain is high-tech, but the way McClane deals with him is low-tech. A fist fight still solves a lot of problems."

Live Free or Die Hard is slated to hit cinema screens next June.
