Speaking of Lee Meriwether! A threefer in a 3rd season Mannix I just watched - Barbara Babcock, Lee, and um, whassisname fro Bread and Circusses.
A Sutton Roley-directed episode! You can tell by the reflection of Mannix in his sideview mirror as Lee Meriwether drives by. Roley was very inventive with odd angles and shots.
