Martha Plimpton on Working with Stephen Colbert in “Company”.

On to a less charged topic: You did a concert production of Company in which you played Stephen Colbert’s wife and had a scene in which you two fought karate-style.
Yeah, he taught me some acrobatics that he’d done in a show with Amy Sedaris, so I basically learned what she used to do. She used to crawl up on his shoulders, and from a handstand he’d flip her onto his shoulders.

You know how to do a handstand?
No, I can’t. He taught me how to do it. And one night, actually — oh my God — he said, “You have to do it with more momentum because I can’t reach out for your legs,” and the next time I did it, I had so much momentum that I almost paralyzed him. I got him clean in the center of the forehead with my shoe. It was bad. It was really bad. I was horror stricken with what I’d done. Luckily he was okay in the end. He just could not have been more patient and sweet and forgiving, thank God. I felt so guilty. I did almost kill him.
