Riverboat (1959–1961)

This was a very good series. In each town the riverboat stopped in, some little drama would take place, with crew members getting involved in the local intrigue. The plots were always watchable and interesting, with occasional but excellent humor, and the acting was first rate. Darren McGavin was dashing as the captain (think Kolchak minus fifteen years).

Darren McGavin was the star of this series. Yet, on his page, he's credited with being in one episode, and on this page appears not at all. IMDb's television series pages used to be pretty accurate, now a lot of stars show as limited guests on their own shows. What happened?
