impact on later directors

Among many other things which make this a great movie,
I think the dialogue is fantastic!
The scene where Charlie is walking Marie home and he's
trying to decide how to ask her to have a drink with
him only to find by the time he finally starts to speak
that she's already left and then he starts to think
about jazz musicians could've come straight out of a
Woody Allen film.
Also, the gansters talking about girls (and Momo about
once wearing his sisters pantyhose) and the modern
gadgets they have (no, really it's Japanese metal!) is
one of the first films I know of to let the baddies talk
like normal people and say things that have nothing to
do with furthering the plot. Something Tarantino would
later take to a whole new level with the Reservoir Dogs
'Madonna' speech.
