Macy explained that the cast is growing alongside their characters, so there’s plenty of new plot avenues to keep the show going.
William H. Macy’s perspective on the situation may cool some heads, although others may still be burning up thinking Emmy Rossum just shortened the run of Shameless with her decision.
Macy indicated to EW he’s not all that worried about that happening, and cited the show’s remaining cast as one of the primary reasons why.
Macy added fans shouldn’t expect a lot of that changing to happen with his character, however, as the point of Frank Gallagher is that he never changes.
