With the success of Rock Balboa, it's not suprising that there is a resurgence of 80's action heroes at the box office. Did nobody learn a lesson from 'Escape from L.A.'? The next Indiana Jones movies has been announced. There's 'Live Free or Die Hard'. Sylvester Stallone is following up with even more.
