"Deep Space Nine" has the honor of being the home of Star Trek's greatest villain – Gul Dukat, played by Marc Alaimo. Beginning as your average power-hungry Cardassian and eventually becoming a DS9 frenemy, a warlord, a madman, and eventually a vessel for the evil gods known as the Pah-wraiths, Dukat displays more growth and change over the course of "Deep Space Nine" than any antagonist in the franchise.
Some interesting and potentially revealing moments in the 2018 documentary "What We Left Behind" suggest that life may have imitated art when it came to Alaimo's relations with the rest of the crew. In the documentary, Nana Visitor recalls being mortified at the suggestion that the writers might create a romance between her character and Dukat while, like his character, Alaimo admits to being attracted to Visitor.
While it's been some time since Alaimo has earned any acting credits, he did make a very interesting appearance in 2020. While the principal photography was completed in 1983, it took 37 years for the horror flick "Grizzly II: Revenge" to finally be released, in which Alaimo not only co-stars with Louise Fletcher — who would go on to play both Alaimo's enemy and lover in "Deep Space Nine" — but with a star-studded cast that includes Charlie Sheen, Laura Dern, and George Clooney.
