According to Wikipedia, A Guide for the Married Man (which co-starred Morse) was a commercial success, but sadly the film version of How to Succeed was not.
However, the same source shows that Robert Morse made at least 15 appearances on network TV from 1954 through 1971 so he certainly was well known to millions of Americans before starring in Sugar, and that doesn't include his performance with the How to Succeed cast on The Ed Sullivan Show. |
