Efron got schooled once again on the set of 2020's Summerland. "At lunch, they served fish," he explained on the Graham Norton Show of the day he was set to get into it with costar Kay Panabaker. "And next was the kissing scene. I was very nervous. We went in for the kiss. I got up this close. I shut my eyes. I'm ready to go in and nothing happens. I'm going further and nothing's happening. I'm getting further and further, thinking eventually we're going to touch. And then I hear, 'Oh my gosh, did you have salmon for lunch? Seriously?'" Harsh, but he learned a valuable lesson: "I carry a toothbrush everywhere I go now."
