Photos:The Expendables 3 cast members & Salma Hayek carry #Bringbackourgirls Sign at Cannes, France.

The "Bring Back Our Girls" message made its way to the Cannes red carpet for the second night in a row.
This time, it was the cast of "The Expendables 3" which includes Sylvester Stallone, Arnold Schwarzenegger, Mel Gibson, Harrison Ford, Jason Statham, and Wesley Snipes who each held up signs bearing the message.

The phrase refers to the worldwide effort to bring home more than 250 Nigerian schoolgirls kidnapped by the extremist Islamic group Boko Haram a month ago. Despite a multinational effort, they have yet to be recovered.

Salma Hayek first brought the message to the red carpet last night, holding up the sign as she arrived to preview her film "The Prophet."

"The Expendables 3" is not an official selection at Cannes, but its stars have made the most of their Cannes visit  arriving on the Riviera yesterday in tanks.
