New Jack City or The Untouchables.
One movie is about Al Capone and his reign of crime in 1930s Chicago. The other is about a crack lord and his reign of crime in late 1980s New York.
There are some scenes and lines of dialogue from the Untouchables that could be re-worked into New Jack City. Remember the scene where Sean Connery threatens to shoot the corpse to get the baddie to talk? I could see Ice-T doing that. Or re-write this line of dialogue from the Untouchables.
"You want to get Nino Brown? Here's how, he pulls a knife, you pull a gat. He sends one of your guys to the hospital, you send one of his to the morgue. That's the New Jack way. That's how to get Nino Brown."
So I see a lot of Scarface comparison's between NJC and the 1983 De Palma film. But I think a more accurate comparison is between NJC and De Palma's 1987 film.
I like NJC a great deal. But personally I'd rank The Untouchables higher.
