Re: Was Lt. Boma going to be a rucurring character?
Don Marshall (Boma) was working fairly regularly in guest shots in those days, and had also guested on Roddenberry's The Lieutenant
. A few years later he got a steady job as Dan Erickson in Land of the Giants
TOS had several guests I immediately recognized during its first run, including Paul Carr (Kelso), and Paul Comi (Stiles). Glenn Corbett (Zefram Cochran) had previously been a regular on Route 66
