And because the man was sometimes overlooked, we'll include the character's full name here: Dr. Roy Hinkley, holder of six degrees.

I was unaware that Dawn Wells died December 30, 2020 (age 82) in Los Angeles, California, USA until I saw her in the 2021 Emmy Award In Memoriam segment. Tina Louise is the sole surviving member of the seven castaways on Gilligan's Island.

Professors of Film & TV

Live Poll: https://www.imdb.com/poll/KJu1ElwHQ-A/

If I may, "Professors of Film & TV" would be Professors who are experts in the field of Film and Television.

Your poll, and a good one it is, is about Professors FROM Film & TV. :)
