Maybe he’ll prove me wrong, but Brad Pitt doesn’t seem the right choice to play Achilles in Wolfgang Petersen’s “Troy.” The hunk they signed to play Hector, Eric Bana (“The Hulk”), is a much better choice.

Here are three reasons why:

1. Hector has always been viewed as the golden boy of Troy, while Achilles was the dark Greek warrior of tempestuous emotions. Despite playing Tyler Durden in “The Fight Club,” Pitt is more of a lover than a fighter. Especially while wearing the kind of gladiator togs that he’ll be sporting in “Troy.”

2. Bana showed in Ang Lee’s “The Hulk” that he knows how to play moody. You know, happy with his woman one moment, ready to kick some Trojan butt in the next. The line that he muttered so well in “The Hulk” — “You’re making me angry. You wouldn’t like me when I’m angry” — is exactly the kind of thing that Achilles would say in his sleep. Not Hector. He’d be too busy polishing his sword while telling bedtime stories to his kids.

3. Bana looks more like Stanley Baker than Pitt. Baker was the Brit actor who played Achilles in Robert Wise’s 1956 film “Helen of Troy,” which I saw as a kid at the drive-in, and after killing the Trojan champion he rode his chariot around the walled city, dragging Hector’s corpse, leering like Jack Palance.

I’m not saying that Pitt as Achilles won’t work. It is what’s usually referred to as casting against type.

Besides, maybe director Petersen can pull it off. If you’re into submarine films, Petersen’s “Das Boot” is still — and I’m wording this carefully — the greatest of them all. I’m being careful because there are still those among us who refuse to admit that German soldiers and sailors were humans, too.

“Das Boot” makes that point, and it makes it with a force that could withstand running silent and running deep.

Here’s a good video bet for the weekend: Errol Morris’ “The Fog of War: Eleven Lessons from the Life of Robert S. McNamara.”

Considering everything that is going on right now in Iraq, not to mention Afghanistan, Morris’ attempt to peer into the mind of one-time Secretary of Defense McNamara is something that every American should watch and consider.

Not that Morris does the best job possible. Nearly every critic in the nation went out of his way to praise Morris’ film, and the movie itself went on to win the Oscar for Best Documentary Feature. But this is understandable. The Motion Picture Academy has ignored Morris for years, refusing even to nominate films such as “The Thin Blue Line” and “Mr. Death: The Rise and Fall of Fred A Leutcher Jr.” And so he was due.

Too bad he collected for this one. Sure, the topic is important. And, sure, Morris does his standard artistic job of mixing shots of dominoes (symbol alert) with combat photos from Vietnam and giant close-ups of McNamara himself. But he leaves out context. It’s one thing to take a view of history and revise it, even deconstruct it. But Morris does neither.

Instead, he lets McNamara ramble along, justifying his actions (and nonactions) as if none of the rest of us had lived through the same era. It still may be too early for any credible history of the time to be written. But those who helped guide it should be forced to explain themselves fully and, as Morris does, not be allowed to escape simply by letting a few well-placed tears fall when the going, and the occasional question, gets tough.
