Ok, so Denzel Washington's push for Oscar glory with 'Flight' didn't quite work out, but he's dusted himself down and got back in the saddle for '2 Guns' - a fairly standard though entertaining looking heist-action movie, also starring Mark Wahlberg. The famous duo play Marcus Stigman and Bobby Trench, two cops sent undercover by their respective departments to investigate separate drug organizations. They don't realise the other is also a cop, though soon figure it out after uncovering millions of dollars from a Mexican drug cartel.
