Christine Baranski revealed to Minnie Driver the “single hardest thing” she’s ever done as an actress.

Baranski was set to topline the Kennedy Center’s revival of the musical “Mame” when she smashed her knee cap and had to undergo reconstructive surgery. But the show still went on and she starred as everyone’s favorite Bohemian aunt.

The interview will air in its entirety on Variety’s “Actors on Actors” Season 6, presented by Shutterstock, which premieres June 13 on PBS SoCal.
