ENTERTAINMENT WEEKLY Presents Dwayne 'The Rock' Johnson at Stan Lee's Los Angeles Comic-Con on Saturda,, October 28, 2017Even The Rock has awkward moments.

Dwayne Johnson has been out promoting "Jumanji: Welcome to the Jungle" ahead of its fast-approaching release date, and while he was speaking to EW, he got to talking about Robin Williams, who starred in the film's 1995 predecessor. It turns out that Johnson became a little tongue-tied when he first met the legendary comedian. After approaching Williams backstage at an event, he made of funny gaffe.

"I finally see him and catch his eye, and I'm like, 'Hey, I just want to say, you are my biggest fan,'" Johnson told EW.

It took an awkward pause for the younger actor to realize what he had said and to then correct himself.

"He just laughed and said, 'It's so good to meet you,' and gave me a big hug," Johnson said. "So that was it. I made an idiot out of myself when I first met Robin."

The mistake is an understandable one, considering what an influential star Williams was. In fact, his legacy is why they made sure to clarify early on that "Jumanji: Welcome to the Jungle" is a continuation rather than a reboot.

"We cannot fill Robin Williams' shoes," Johnson said. "That's impossible to do."

"Jumanji: Welcome to the Jungle" opens Dec. 20.
