Assassination Tango (2002) 3

Duvall plays a pony-tailed hitman hired to go to Argentina and bump off some general. He gets to Buenos Aires, Argentina, but runs into a snag. The general has suffered an injury and won't be coming to town for a while.

Duvall has to kill time and since he is a dance devotee, he goes to a tango dance parlor. He becomes friends with a tango dancer and spends lots of time with her and in long conversations about the tango.

He finally moves toward the completion of his contract. I won't tell the end as that may spoil it for you.

I found it interesting, but I realize that some people might find it deadly dull.

I guess that Duvall in real life is a tango fan and this is the reason for the flick.
