The Daniel Craig starrer has earned a massive $507.9 million internationally and $161.3 million in North America, a media report said.
The Sam Mendes directed film is well ahead of the $599.2 million earned by 'Casino Royale' in 2006.
The success of 'Skyfall' has been a boon for Sony, which is enjoying a record year. Sony is releasing and marketing the movie on behalf of MGM and EON Productions.
Sony chairman of worldwide marketing and distribution Jeff Blake announced that the studio has crossed $4 billion in global tickets sales for the first time in its history.
The studio's previous best was $3.6 billion in 2009. Sony's 2012 slate also includes 'The Amazing Spider-Man' with $754 million worldwide, 'Men in Black 3' with $ 624 million and 'Hotel Transylvania' with $283 million.
“Exceeding $4 billion globally is a true rarity in this industry and it is an extraordinary accomplishment for all of us at Sony Pictures,” Blake said.
