While both are handsome actors with dark hair and features, they don't have a strong resemblance. Jerry Trainer is played by Jerry Trainor, and he has a more comedic and goofy look, often sporting a mustache and a more "average guy" appearance. Ian Somerhalder, on the other hand, has a more intense and brooding look, often portrayed as a handsome and mysterious character.
So, while there might be some similarities in terms of their attractiveness, they have distinct features and overall appearances. It's more likely that you're seeing a shared quality in their appearances, like their dark hair or facial structure, rather than a strong resemblance.
