Half Past Dead (2002)
'The Good. The Bad. And the Deadly.'

Of course you see the trifecta of Seagal posters here. Blue tint, closeup and holding a gun. I can only assume Seagal plays an undercover FBI agent here (the plot summaries on it are sketchy) which fits the character formula. I'm not sure about much else on the plot, but the poster being so perfect makes up for any possible plot missteps such as lack of terrorists or drug dealers and nobody Seagal knows getting killed.
