Elisabeth Moss described her one-time Broadway co-star Jeremy Piven as "unprofessional" for abruptly dropping out of their production of "Speed-the-Plow."
"That's a very good one. I could go on and on, being highly unprofessional," Moss replied when asked about why Piven exited mid-way through the production.
"We were all surprised. It came out of nowhere. He just didn't come back one day. ... I saw him like a month later at the Golden Globes, when he was supposed to be really sick."
Norbert Leo Butz and William H. Macy ultimately replaced Piven in the show.
Piven is a former star of "Entourage," who can now be seen in "Mr. Selfridge."
