Why not. And instead of descending down the aisle, he's going to wade out of a purpose built lake, with a white shirt clinging to his contours.

The actor whisked his fiancée Amal Alamuddin away for a romantic break in the English countryside this week, which took in Highclere Castle near London - where the period drama is filmed - and she was so taken by it, they made enquiries as to whether it could be used for their wedding.

A source told MailOnline: "George became close friends with Hugh Bonneville, who plays Lord Robert Crawley, when they did The Monuments Men together last year. And they really hit it off. He contacted Hugh and asked him to arrange a private tour of the castle. Amal was blown away. When he saw his bride-to-be's reaction to the spectacular Victorian castle, set on 1,000 acres of parkland, he began making some discrete inquires about having their wedding performed there. And he was told they would be most happy to accommodate them."

Highclere is thought to be a good venue for the wedding as it is close to London and also to Heathrow airport, meaning George's family from America can easily fly in, as can Amal's extended family who live in Dubai and Lebanon.

The castle is currently inhabited by the 8th Lord and Lady Carnarvon and they allow weddings, with prices to hire parts of the castle starting at $23,000 for a day. Bargain.

The source added: "George loves the idea of marrying at the castle, because it's a glamorous place he could secure... Amal's Middle Eastern relatives would most certainly enjoy the exhibition, and the tour would make for a most memorable wedding."

Other venues the couple are said to be considering for the wedding are George's home in Lake Como, Italy, and Cabo San Lucas in Mexico, but it is thought Amal wants to be near where she grew up in the UK.

Another source said: "Amal grew up in London, and attended school in Buckinghamshire. And she went to University at Oxford. She currently works in London so she has many close British friends."

He'll never handle the weather, but sure that's for another day.
