4.5 Arnie ArnieP | 25/05/2007 | See all ArnieP's reviews (2) Great Film. Quality story - based on an Asian Classic - Infernal Affairs. Jack as good as ever. Great performances from Leo and MarK Walberg & the entire ensemble cast. Nice script, twist and everything else you hope for in a movie of this type. Great sound track also. So good in fact that i've even risked buying ou Blu-ray!!!! If you like Goodfellas & A Few Good Men then you'll love this.
