Mark Wahlberg & Denzel Washington are undercover agents playing each other, until they both get double-crossed and have to work together. While the plot is typical, there are enough variations to keep it interesting. The chases and fights are competent without being exceptional. What makes a film like this work is the chemistry between the leads and these guys got it! The snappy banter helps a lot (this may be Wahlberg’s best comic performance). Don’t go expecting more than basic summer action fare and you’ll be mindlessly entertained.
