No matter how many awards you snag, auditioning for your next project is typically par for the course, but with big films such as "Baywatch," "The Greatest Showman," and the "Neighbors" franchise under his belt, you might think Zac Efron would be a pro at first impressions. Think again.

While trying out for the role of charming hearthrob Link Larkin in the 2007 movie adaptation of Hairspray, a young Efron already seemed like a shoe-in, but he almost didn't make the cut. According to Efron, Director Adam Shankman actually thought the actor smiled too much. (Did you think it was possible to see too much of those attractive pearly whites?)

Efron reportedly tried to tone it down, but that only made things worse. "It was impossible. Because I was such a smiley kid, I couldn't do it," he told Cosmopolitan (via People). "It took me like four or five tries and [Shankman] was just shaking his head and making fun of me the whole time." 

We'd definitely be the last ones to complain about Zac Efron smiling too much.
