Can Elmah handle an exception thrown before controller action execution?

Question

I'm using Elmah to log exceptions, and have been going nuts due to customers complaining about getting errors, but I don't see any 500s in Elmah's log.

The exceptions are occurring inside some attributes on model properties, when the model is being validated. Obviously there's something wrong with my validation which I can fix, but I'd still really like Elmah to log these things if (when) they come up again.
