Loan Gruffudd is a Welsh actor. He first came to public attention as Fifth Officer Harold Lowe in Titanic, and then for his portrayal of Horatio Hornblower in the Hornblower series of television films.
These are in my opinion the best and worst Superhero comic book castings in the MCU, DCEU, Arrowverse and others. I will be including actors who have played villains and supporting characters. THIS IS ONLY MY OWN OPINION.
