“He’s a really, really infinitely interesting man,” actress Glenn Close raved to Closer last September, referring to her then-husband, biotechnology entrepreneur David Shaw.

Glenn and David in December 2013.

The six-time Oscar nominee — who’s played everything from grand dames to lawyers to psychos — has had her share of failed romances.
