"Nobody knew it was me. Then the woman on the mic asked for a volunteer to pick a name out of a hat that would get a special meet-and-greet with 'Ansel' and I raised my hand to come pick a winner," Elgort recalled in the video caption. "Unfortunately, she yelled my name before I made it down to surprise everyone but it was still epic!"
"Instead of one winner, there were 200!" he added. "Loved meeting you guys and watching the movie with you too! I was so nervous somebody would notice me and distract everyone watching the movie for the first time! Can't wait for everyone to see Baby Driver."
Elgort has been receiving critical acclaim for his starring role in Baby Driver. The film follows a young getaway driver named Baby (Elgort), who finds himself taking part in a heist doomed to fail after being coerced into working for a crime boss (Kevin Spacey).
