Well, Maharis had that hepatitis bout in the latter half of second-season, leading to a spate of Milner-only episodes, then came back for third-season, but then bowed out again mid-season. A buddy of mine who interviewed Stirling Silliphant related to me that Leonard, who had a lot of high hopes wound up in Maharis got really put out with him, and implied it involved some homo shenanigans.
Oddly enough, I tend to rather like the Corbett episodes (and I seem to be in a minority on that), even though it altered the seeming chemistry of the series. Anyway, whenever I’ve met actors who’ve appeared in the show (Elizabeth McCrea, Anne Helm, Veronica Cartwright, etc.), I always have asked about their experiences on it. The on-location work always seems to make them memorable to folks.
The episode I remember most ( I was just 9 ) is Good Night Sweet Blues with Ethel Waters . At the time I had no idea who she was , or other jazzers who starred : Coleman Hawkins ( of whom I became a big fan ) , Roy Eldridge and drummer Jo Jones , who , ironically , wasn’t the drummer in this ep !
