B&B co-star
Winsor Harmon once starred with McCook on an episode of
Acapulco H.E.A.T. filmed in
Mexico. Harmon told
Soap Opera Digest about their guest stint on
H.E.A.T.: "I hung out with John McCook the whole time and I kept watching all these people from other countries asking for his autograph. I'm thinking to myself, 'Who the hell is this guy?' So one night, we were drinking
Coronas and I asked him why he had so many fans and he explained how
B&B was so popular around the world. I had no idea. The more he talked about it, the more I was thinking, 'I want to be on that show.'... The first time I drove into the parking lot, there was John, just pointing at me and laughing. He asked what I was doing here and I told him that I was
Thorne. That's when he told me that he was going to be playing my dad. That was just too wild." In 2001, 2012, and 2018, McCook received a Daytime Emmy nomination in the Outstanding Lead Actor category for his portrayal of Eric Forrester. In 2022, McCook won the
Daytime Emmy Award for Outstanding Lead Actor in a Drama Series for the same role. ==Personal life==
