How is his name pronounced? Help!

Calling all Aussies! Can somebody PLEASE tell me how his last name is pronounced? I wondered about it for a long time, until I saw the trailer for The Hard Word. They said Egger-ton. I thought, sweet, so it is. Maybe a little different from what I thought, but there.

And now, NOW I watch the trailer for All the Way, and they say EDGER-ton! It sounded so bad! But maybe it’s right? I’m hoping Americans just messed it up, since this –as we know – isn’t the original thing anyway, but the American version. Off hand, I cannot find a trailer for “The Night We Called it a Day” (I was hoping it would be an Aussie announcer who knows what he’s doing and who knows the proper pronunciation of, well, the movie’s leading actor).

I’m confused and frustrated. (Somebody call the wambulance.) Any help would be much appreciated.
