WATCH: ‘Superman’ Actor Suggests Trump Supporters Are ‘Not American’

“Superman” actor Sean Gunn, brother of film director James Gunn, doubled down on his brother’s political messaging behind the upcoming blockbuster by seemingly suggesting that Trump supporters and all those opposed to mass immigration are “not American.”

In a recent interview with The Sunday Times, Gunn stressed that the film will be political and suggested that those who take issue with it should not buy a ticket. “”Superman is the story of America,” he said. “An immigrant that came from other places and populated the country, but for me, it is mostly a story that says basic human kindness is a value and is something we have lost.”

Superman was first introduced as a character by writer Jerry Siegel and artist Joe Shuster in 1938. In the comics, Superman is the lone survivor of the planet Krypton who was sent to earth by his parents just before their world was destroyed.

Gunn has spent the film’s promotional period seemingly arguing that the fictional character’s story should be adopted as a political policy in the United States. When asked how the movie — which is set to serve as a reboot of 2013’s “Man of Steel” for the D.C. Universe — will play in a gridlocked country, the director acknowledged that there is a contrast.

“Yes, it plays differently,” he said. “It’s about human kindness. And obviously, there will be jerks out there who are just not kind and will take it as offensive just because it is about kindness. But screw them.”

After his not so subtle jab at President Trump and his supporters generated outrage online, Gunn stood by his comments while speaking with Variety magazine on Monday. “I’m not here to judge people,” he said at Monday night’s “Superman” premiere at Hollywood’s TCL Chinese Theatre. “I think this is a movie about kindness and I think that’s something everyone can relate to.”

The director’s brother Sean, who plays Maxwell Lord in the film, took things a step further by suggesting that those who object to the politicization of the superhero flick are “not American.”

“My reaction to [the backlash] is that it is exactly what the movie is about,” he said. “We support our people, you know? We love our immigrants. Yes, Superman is an immigrant, and yes, the people that we support in this country are immigrants and if you don’t like that, you’re not American. People who say no to immigrants are against the American way.”

Actor Nathan Fillion, who plays Guy Gardner, aka Green Lantern, joined Gunn in mocking those who reject to the politicization of a superhero movie primarily marketed to children. “Aw, somebody needs a hug,” Fillion said. “Just a movie, guys.”

“Superman,” which stars David Corenswet and Rachel Brosnahan, is set to hit theaters on July 11. With a hefty budget of $225 million, the film will need to generate more than $700 million worldwide in order to be considered a success.
