Hard to Kill (1990)
'Nico's back and this time he's even more harder to kill.'

Seagal plays a cop here and 'Hard to Kill' follows the naming conventions. The poster is also doing well, though perhaps the presence of the girl detracts from Seagal holding his gun, he is obscuring the majority of her body, so I guess it works out. The plot involves some bad dudes killing his wife and nearly him as he goes into a coma. However once he comes out of the coma he hunts down his wife's killers and snaps all their necks like so many discarded chicken bones.
Marked for Death (1990)
'In Above the Law, he got tough; In Hard to Kill, he got even; Now the man with the short fuse is... Marked For Death.'

Poster is a nice closeup of Seagal holding a knife instead of a gun but there's also a silhouette of Seagal holding a gun to make up for this travesty. The poster is tinted red, which goes against the grain, but the title and plot and character fit perfectly so we can forgive that. Seagal plays a DEA agent whose partner is killed and he must hunt down his partner's killer ... or some guy named Screwface ... either way Seagal doesn't get hurt and kills a lot of drug dealers!
