I like the Brad Pitt version
Interestingly, so does Eric Cline, the guy who wrote
1177BC: The Year that Civilization Collapsed. He actually thought it was pretty good, and he's one of the foremost scholars on the Late Bronze Age around today.
Here's the start of a great series of lectures he does on the Trojan War:
In answer to the original question, the single combat thing was more an artifact of the Bronze Age than of Classical Greece. I doubt you can find many, or even any Classical Greek accounts of champions or leaders dueling like that. The combats depicted in the Iliad and the battles depicted in
Hoplite are at least 500 years and a Dark Age apart. Hector wasn't a historian, he was a poet who wrote down an oral tradition 500 years old. Assuming there even was a single "Homer."
Anabasis isn't full of that kind of fighting. It reads much more like an account of an early modern campaign. You don't find that in Thucydides. In fact, you don't find it in any of the first-hand accounts we have of the Battle of Kadesh, which took place within about a century of when the Trojan War happened (assuming it happened at all). Instead you have well ordered and mutually supporting formations of chariot cavalry fighting a recognizable meeting engagement.
Were there ritualistic fights between champions in Bronze Age tribal cultures? Yep, I'm sure there were. The pre-Classical Greeks may have even engaged in some of that during any conflicts they had with the inhabitants of the coast of Asia Minor. None of that really existed by the time of Classical Greece though, when hoplites were trained to fight in close order and constituted the world's first heavy infantry force.
The actual Late Bronze Age is a pretty fascinating period, by the way. Much more interesting than the myths handed down over centuries that have ended up as popular entertainment.
1177 BC is well worth the read.
