K.J. Apa said that for all the scenes where he's eating junk food with his friends at a diner and eating burgers, he has a bucket just off camera where he spits out all the food after taking a bite for the camera shot.

K.J. Apa said that he does not mind being shirtless and showing off his abs on the show because that is how the character is written in the script. He said, "Someone has to have abs on the show. It's always strange to play a sex object. But when I read the script, it was how they were taking it. So I was prepared for that, and I knew that people were going to take it like that as well. But yeah, it is strange. I don't think it's anything I'm ever going to get used to. As soon as you get used to becoming a sex object, that can be dangerous. When people look at you as a sex object, that's not how you're defined. There's more to Archie than abs and his body and getting with girls. He's a humanized character, and people should see past that, but initially, at first glance, people are going to have that first impression of sex object."
