How about a guessing game?

Um, good guess, but nope.

Fifth clue coming up mañana.

Good Golly Miss Molly, took you long enough!

Yes, it was none other than TE Lawrence, as depicted in the epic and classic movie, Lawrence of Arabia.

To review the clues:

1) One of the characters is a real bastard.

Yes, TE Lawrence was the child of an unmarried couple. The father was knighted but as Lawrence explains to Ali near the beginning of the film, that didn't give Lawrence a title since his parents were not married. In effect it makes TE Lawrence a bastard, in more ways than one.

2) The Bastard is a peacemaker who finds he enjoys killing.

This is where the extra bastard comes in. Lawrence seemed to have a horror of bloodshed but at one point he has to execute a man whose life he had previously saved. He confesses later that it troubled him, not because of the violence, but because he found he enjoyed it. Later he succumbs to blood lust during a massacre of Turkish troops on the run, to the disgust of his companion Ali (played by Omar Sharif). Hence the more ways than one he was a bastard. Had the movie not been guessed, I probably would have used the "No Prisoners!" cry of Lawrence as a clue.

3) The Bastard enjoys donning exotic garments.

Should be self-explanatory. When Lawrence dons the white robes and gold headpiece of an Arabian warrior, he revels in it, dancing around in the desert.

4) Fourth clue: The movie has memorable theme music.

Yes, once you've seen the movie that theme music will always ring a bell. Well, it does for me, anyway.

5) The events the movie depicts take place, mostly, during WWI.

The struggle of the Arabs against the Turks, who had dominated the peninsula for a long time, was central to the movie, and part of the wider struggle of WWI, since Turkey was allied with Imperial Germany. The movie opens with a "flash-forward" of Lawrence back in England at the end of his life,  around 1935, when he gets on his motorcycle, swerves to avoid boys riding their bicycles on the wrong side of the road, and perishes.

6) The main character led a successful guerilla war.

It may have been the first use of guerilla tactics in modern history. The Arabian tribes were somewhat unruly and independent, and would not have worked well under a rigid military structure such as the English and French wanted to impose upon them. Lawrence saw this and instead formed them into an "Arab Army" which engaged in lightning attacks and sabotage, and wound up being the first forces to take Damascus from the Turks.

7) The main character was an archeologist.

As a youth TE Lawrence was interested in antiquities. He became well educated despite his compromised social position, and did archaeological work in the Middle East from 1910 to 1914.

So there you have it. BB beat me to the finale here, that's OK, but I did want to go over and enlarge upon the clues and how they pointed to this great film.

PS-I chose this movie sort of by accident. I was thumbing through my alphabetically arranged movie collection on DVD, without much luck, when I saw this movie, Lawrence of Arabia, sitting on top of the bookcase awaiting to be put into the proper location. It didn't take long to realize that it has a rich set of circumstances from which to devise a puzzle.

OK, got it.

Here's the next movie puzzle.

Another film classic.

Set in the good old USofA. In the West, but it's not a Western.

Famous Actor A insisted that unknown Actor B be given a part, which basically launched a very successful film career for Actor B. Actor B was eternally grateful to Actor A.
