During filming The Love Boat in 1979, Harmon donned an oh-so-’70s style.

Harmon tells Variety about his early acting days, saying, “If you needed someone to take his shirt off and kiss the pretty girl, I was the guy to call. It was me if you needed someone to say, ‘Ma’am, can I see your license?’ and then get shot.”

Harmon made everyone melt as the handsome cosmetic surgeon Dr. Robert Caldwell on the medical drama St. Elsewhere from 1983 to 1986. His character’s journey made history when he became one of the first major network television characters to contract and die of AIDS.

Harmon told Variety of his role, “At the time it was really risky, but years later it was something people talk about and remember. What they were saying about that character was simply not being done at that time.”

Harmon quipped on SNL (Saturday Night Live), “It’s been a lot of fun doing this show the last week, except for one problem. As the week progressed, I saw that I was wearing less clothing than everyone else in every sketch and began to worry that I was being used, you know? This is a problem I’ve had since 1986, when I was named PEOPLE’s Sexiest Man Alive.”

Mark expressed similar comments in 2017, telling TV Insider, “It’s just who we are. We remain at home. A lot. I’m not a fan of Twitter or Facebook. Our sons aren’t interested either. Pam and I have both made a livelihood in this field, yet there is still a part of it that isn’t natural.”
