“[The] most fun [part] was creating two different characters and allowing them to live in moments together,” Hudgens told Newsweek. The “most challenging was going back and forth in a scene shooting out both characters. It was a little confusing but a fun challenge.”

Rudd told "CBS This Morning" that playing two roles on the Netflix show "was a challenge."

"For me, the way it worked best was to record the audio for both characters," he said. "Whatever character is driving the scene is the one they would film first. I wouldn't act with a double or an acting partner, I would put a little earwig in my ear, I would listen to the opposite line."

He continued: "If I'm playing the new version of the character, I can hear the old version replying because there's somebody off-screen hitting the cue."
