Dean Cain rails against James Gunn's recent comments about his new 'Superman,' claiming it 'was a mistake' for the filmmaker to link the iconic hero to the immigrant experience.

Some fans have long thought of Superman as an immigrant character, as his displacement from his fictional home planet to the United States is a key part of his story.

"I truly hope this film brings friends and families together, brings people joy, moves people, as it has done for me, and as the experience of being a part of making the film has done for me," she continued. "I love you @jamesgunn, I love your film, and I love all of the wonderful people you have brought into my life. #superman."
