Preparing for a World Cup is surely a stressful experience, but these rugby stars look relaxed while filming this brilliant new promo.

Conor Murray will face off against England captain Chris Robshaw in Twickenham, on Saturday, but chats about their acting skills may be lumped on the back-burner. In a world where Lucozade Sport is only available to the home nations of Scotland, Ireland, England and Wales, southern hemisphere players will, we're told, go to extreme length to get their hands on the stuff. If you've ever wondered what Bryan Habana looked like in a kilt or what Drew Mitchell's Robshaw impression was like, just check out the video below. We suspect that a Hiberno-centric version will soon be released and feature Murray as the main man. The genuine legend of the whole piece must be South African winger Bryan Habana, who not only cracks out an on-the-money Braveheart speech but [badly] sings The Proclaimers' '500 Miles'.
