Penelope Cruz was in costume yesterday to shoot her movie Venuto al Mondo in Sarajevo. Her look also included a wig that featured some gray streaks. Penelope arrived in Bosnia last week to work and brought along her son, Leo, and husband Javier Bardem. Security on Penelope's movie is tight, but that hasn't stopped photographers from getting a glimpse of the star in action. She's been logging long days on set; though, her nights have been free for family fun. Penelope, Javier, and Leo got ice cream earlier this week while out exploring their temporary homebase.
