JoBlo has revealed that 20th Century Fox is planning on showing the teaser trailer for Live Free or Die Hard this weekend in select theatres.

The trailer would run before prints of Blood Diamond - but not all prints. The trailer, of a still undetermined length, will only run before 35mm prints of Blood Diamond with Fox showing a trailer for Pathfinder for digital prints.

If this is the case, then it would seem likely that the trailer would be posted on the web sometime early next week.

The film stars Bruce Willis, Justin Long, Maggie Q, Timothy Olyphant and Mary Elizabeth Winstead.

The fourth installment of the franchise finds hero John McClane (Bruce Willis) coming out of retirement to battle an Internet terrorist organization. Aan attack on the country's computer infrastructure begins to cripple the nation. But the man behind the attack never expected an old-fashioned cop to mess up his plans.

Live Free or Die Hard arrives in theatres on June 29th, 2007.

Live Free or Die Hard was released June 27th, 2007 and stars Bruce Willis, Timothy Olyphant, Justin Long, Maggie Q, Cliff Curtis, Jonathan Sadowski, Andrew Friedman, Kevin Smith. The film is directed by Len Wiseman.
