In January 2003, Warner Bros., producer Brad Grey, and actor/producer Brad Pitt bought the rights to remake the Hong Kong film Infernal Affairs (2002) from Media Asia for $1.75 million.
Andrew Lau, the co-director of Infernal Affairs, who was interviewed by Hong Kong newspaper Apple Daily, said: "Of course I think the version I made is better, but the Hollywood version is pretty good too. [Scorsese] made the Hollywood version more attuned to American culture."
Andy Lau, one of the main actors in Infernal Affairs, when asked how the movie compares to the original, said: "The Departed was too long and it felt as if Hollywood had combined all three Infernal Affairs movies together." Lau pointed out that the remake featured some of the "golden quotes" of the original but did have much more swearing. He ultimately rated The Departed 8/10 and said that the Hollywood remake is worth a view, though according to Lau's spokeswoman Alice Tam, he felt that the combination of the two female characters into one in The Departed was not as good as the original storyline.
