Well, maybe he didn't exactly get the idea from 300, but that's what it immediately reminded me of.  Could the Nodding Horsehair Crest become the newest male fashion?  Will men stay up half the night, destroying the ozone layer with can after can of Aquanet in a vain attempt to persuade their coiff to march with erect Spartan precision down the center of their scalp?  Might there be a Leonidas variation, chopped in half?  And who publicly admits to watching American Idol, anyway?

Unanswerable questions, all.

Let's sample the internet to see what people are saying about David in 300:

My favorite line, by Dilios, "...to save the world from mysticism and tyranny!" Not exactly a meaningful line, but the way Dilios said it made it so unforgettable (at least for me!)

The film's final summation (is) delivered beautifully, with hitherto unseen modulation and evenness by David Wenham.

DUDE, David Wenham's in this movie = SO GREAT. I love him, and I didn't know he was in this, so it was a delightful surprise.

I can't pass up the opportunity to watch David Wenham with an eyepatch! HE HAS A FRIGGIN EYEPATCH! That's AMAZING! I love that red-haired Australian! I really really do! :D I had no idea he was in this movie and I seriously started squealing when I recognized him. Sam gave me the "girl please" look, but then came over to my side as the movie went on. She's all about Gerard, but I'm all about the man with the patch. FARAMIR!!!!!!! I LOVE YOU!!! MY LOVE FOR BOROMIR SHIFTED TO YOU BECAUSE YOU'RE LIVING!!!! Really though, I adored Faramir, and now I love Dillios. Thank you David Wenham. You are my god :P.

David Wenham's character, Dilios, in 300 had a very important role. While not showcased in battle like the other supporting characters of Astinos, Captain, and Stelios he had, possibly a more challenging role. He was the narrator. He was the voice of the story, the giver of background and insight, but more than that it was his character's duty to bring closure to the movie. No small feat for something so epic and grand.  He had to take all the momentum and adrenaline and bring it to an equally fitting conclusion. Well done in my opinion.

I thought the narration was nothing short of exceptional. Very distinctive - I was suprised after the first few minutes, when it showed him, how young he was - at first I thought it must have been a voice-over.

Great voice for a movie, but I hope he doesn't talk like that in real-life - imagine that at the McDonalds drive-thru first thing on a Sunday morning! The operator would be thinking he's still tripping from the night before.

Anyway yeah, very good work David! A new Burton if you ask me :)

Honestly, he's proven himself many times over. He was great in Van Helsing, 300, and Lord of the Rings. Let's stop tossing him supporting roles and put him in another fantasy/action role, but this time in the lead. He's quite the capable actor.
