Rhea Seehorn: I wore a real cast for Better Call Saul

The Hollywood Reporter

"It's a real plaster cast that was applied by a paramedic two hours before I'd start work," she says. "You'd let it dry, you'd keep it on all day, you'd have it sawed off at the end of the night when everybody's done. It does not come on and off between scenes, or to go to the bathroom or to go eat. We tested other things. Some of the clip-on ones looked too bulky, some of the other ones, if you shoot in our very cool lighting and cinematic set-ups that (director of photography) Marshall Adams does, then the plaster looks fake if it was the plastic ones. It was all sorts of things that went into why it was best to do it, and then they checked with me for my comfort level."
