investigation Friday following the online release of a short film showing two men having sex at the ancient Acropolis in Athens.The 36-minute movie, titled “Departhenon,” was released on Dec. 21 but came to the attention of authorities this week.The Culture Ministry said it did not give permission for the Acropolis film shoot.“The archeological site of the Acropolis is not suitable for any kind of activism or other activity which would cause offense and displays disrespect for the monument,” the ministry said in a statement.The movie contains several explicit scenes involving male and female actors whose faces are not shown.
