Writer-director Jordan Peele sat down with Stephen Colbert on Wednesday night’s episode of “The Late Show,” and shared his thoughts on his thriller film “Get Out” receiving a Golden Globe nomination for best musical/comedy.

“I submitted it as a documentary,” Peele told Colbert, echoing a tweet he posted earlier on Wednesday, which read, “‘Get Out’ is a documentary.”

“Here’s the thing, the movie is truth,” he continued. “The thing that resonated with people was truth, so for me it’s more of a historical biopic.”

The nomination of Peel’s film, which was billed as a thriller and deals with racial tension in the United States, caused some confusion on social media. With only two categories available at the Globes — drama and musical/comedy — decision-makers can have trouble selecting a category for some films. Matt Damon-starrer “The Martian,” which is about a lone astronaut surviving on Mars, was also nominated in the musical/comedy category in 2015.

Colbert also remarked on the fact that ‘Get Out’ has a 99% rating on Rotten Tomatoes, and asked Peele what he thought the missing 1% was.

“Racism,” the actor responded.
