In honor of the release of the Coen brothers’ “No Country for Old Men,” Entertainment Weekly created a list of the greatest hired killer characters in movies. As with all lists, it’s a conversation-starter, not ender. Some good choices, of course, especially Jean Reno in “The Professional” and Travolta and Jackson in Pulp Fiction. The choices are classic, I suppose, but a little obvious. Some of the lesser-known movie hitmen who are well worth a look include William H. Macy in Panic and Lee Marvin’s Oscar-winning performance in Cat Ballou.
