Every so often, a background or supporting character does such a good job at stealing scenes from the stars of a show or movie that Hollywood has no choice but to take notice. And sometimes, they’re given the chance to shine in their own spinoff. We know the success stories (Frasier Crane and Saul Goodman come to mind) and the flops (Joey, we had such high hopes), but bit players have been proving their worth at the top of the marquee for decades, often shining brighter than their original incarnations.
