That's a shame, but I think there are plenty of precedents of male actors who have likewise done stupid shit because of the bottle, but have gotten help to get out of it, and given second and third chances.
Yeah, she still looks good.
There are many older actresses that still do look great, and who aren't used as much as I think they should be.

I think it's sad that Hollywood continues to make so many movies with elderly gents in the lead role, but never do you see an elderly woman in a lead role. Even the great looking ones.
