The world’s most famous bachelor welcomed more A-list stars to Venice on Saturday for his wedding to the human rights lawyer, with details of the long weekend bash kept as hazy as the morning fog over the Grand Canal. The official ceremony is expected to be held on Monday at Venice’s town hall, the 14th-century Ca’ Farsetti palace, and Italian media reported that the former mayor of Rome, Walter Veltroni, a film buff and Clooney friend, would officiate.
