Note to world leaders: Next time you need instant access to foreign dignitaries and top military brass, forget the usual protocols. Just send in Angelina Jolie.

Hollywood's globe-trotting leading lady swooped into Baghdad on Thursday to highlight the plight of Iraqi refugees, gaining an audience with Gen. David Petraeus, the top U.S. commander in Iraq, and Iraqi Prime Minister Nouri al-Maliki, the American Embassy said.

On her mission as a U.N. goodwill ambassador, Jolie also met with Iraqi migration officials to stress that there needs to be a coherent plan for the more than 2 million internally displaced Iraqis who are beginning to trickle back to their homes amid a recent lull in violence.

Jolie mingled with American troops during lunch at a dining facility in the heavily guarded Green Zone, which houses the embassy and Iraqi government offices.
