In the movie Die Another Day (2002), Miranda Frost (played by Rosamund Pike) wears a pair of black Ray-Ban RB4122 sunglasses. The glasses can be spotted when Frost is waiting for Gustav Graves to arrive at Buckingham Palace in London.
The glasses have a black frame (code 601) and the lenses are most likely grey-green (code 71) but could be grey gradient (code 8G). These sunglasses are currently not produced anymore by Ray-Ban, but can be found on some online stores and eBay. Other colors, including a red (code 735) framed version were also available and can still be found on Amazon.com or eBay.
