E! Online har ett citat från kostymdesigner Deirdra Govan :
Mr. Blank's finalized look, which includes a bowler hat and eye patch, was a combination of how Boots and Deirdra saw the character. Boots wanted to use a leather shop in Oakland for the patch and Deirdra pushed for the hat.
"Mr. Blank was a really interesting character, in that he has no backstory," the costume director shared. "He's just a man that appears. For me, having studying art history and understanding surrealism, the film itself is very surreal. I took that straight to the place in Renee Magritte. You have a man that has no clear name. Even though we see his face, he's still a man without an identity."
