Remnick conceded that the festival was not the best format in which to interview Bannon, and that it could be done "in a more traditional journalistic setting".
"But Bannon has already exerted enormous impact on Trump; his rhetoric, ideas, and tactics are evident in much of what this President does and says and intends", he added.
Bannon, who was once the chairman of Breitbart News, is a featured speaker at the festival and many voices in Hollywood have spoken out against his inclusion.
"I will not take part in an event that normalizes hate", Apatow said via Twitter, calling on the magazine to cancel Bannon's portion of the event.
Carrey, whose Twitter feed makes his distaste for the Trump administration crystal clear, also said he was bailing due to Bannon, tweeting that seeing him and Bannon together on the same program is something that "could never happen".
Steve Bannon is known for his alt-right views that many in the public have linked with white supremacy. He also acknowledged that guests at the festival, unlike those interviewed on radio or for a story in print, are paid an honorarium along with money for travel and lodging.

"To interview Bannon is not to endorse him", David Remnick said.
Since leaving the White House a year ago, Bannon has continued to champion right-wing causes, including supporting British anti-Islam activist Tommy Robinson, who was freed from prison last month after winning a legal challenge over contempt charges. I hope @NewYorker keeps me in mind for future, "winking white nationalist cyst-goblin"-free events? Ahead of the mid-term elections and with 2020 in sight, we'd be taking the opportunity to question someone who helped assemble Trumpism". Now, New Yorker is selling tickets to see him headline.
Musician Jack Antonoff said he hadn't been told about Bannon's invitation when he accepted his own. "In what I would call a defining moment, David Remnick showed he was gutless when confronted by the howling online mob".
