Ummm, They're All Terrorists or Sympathizers
It's hard to get excited about the trials & tribulations of what are basically a bunch of terrorists. Even Paul Newman's character ends up killing in a big jail break to free what was basically Israel's Osama Bin Laden. If this was done nowadays the Sal Mineo character would be an Iraqi "freedom fighter" trying to blow up US jeeps on the road to Mosul.
