Of course, there's Joan.
I learned of Constance Bennett from here.
I *believe you've also mentioned a Bennett Brother/actor. I'm scrolling through tomorrow's movies (because, AGAIN, they're showing 'Supernatural' eps which they just showed less than a week ago???).
I see "Dark Passage", which I've seen before, the info says Humphrey Bogart, Lauren Bacall, and Bruce Bennett.
Is this the brother??
