'The Boss of It All' is the other credit that tends to come up. She has worked in comedy more often than in any other register. There are 33 entries on the filmography, most of them supporting work in other people's stories. Ask a viewer to place Louise Mieritz and the answer usually comes back 'The Idiots'.
