Lunchtime on Mercury

Just watched a very good 100% CGI documentary on the Solar System, with Elf and the boys. The voice over was an Englishman with a very serious, almost metallic voice. We have a DVD about tigers that is also gravely narrated by this fellow. He had just spoken about the wild extremes of temperature on Mercury: −183 °C at night to 427 °C during the day, I believe. Marcus said "Hmm, it would be fairly nice at lunchtime".
