Bogart's Irish accent...eeeek

Having Bogart affect a brogue was a mistake - his name is enough to tell us he's an Irishman.

In my case, self-absorption is completely justified.

it was funny

His accent is not convincing but I thought the scene in the stable where he learns she is dying was pretty good. We don't see his face but the way he tracks her face and responds physically to the news was, I thought, a good example of an actor wholly in the role and not just waiting stiffly for his next shot or to say his next line.
