The lead actors of “The Hangover” are big stars now, but they were mostly up-and-coming at the time. Bradley Cooper wasn’t yet the man who would direct and star in Oscar-winning films like “A Star is Born.” Zach Galifianakis had not fully revealed himself to the world as the comedic genius that he is. Even behind the camera, this was years before Todd Phillips would direct $1 billion hits like “Joker” and the upcoming “Joker: Folie a Deux.”

Helms, meanwhile, was on one of the most beloved shows on the air at the time, “The Office,” playing the role of Andy Bernard. That character, rather notably, had all of his teeth. As a result, Helms agreeing to have his tooth pulled created challenges for the show. As Helms explained:

“I talked to my dentist and he said, ‘Yeah, we can take it out.’ He was a champ. He’s in the credits. So he took the tooth out, and he had to make a special piece to then screw into the hole so that the gum tissue stays healthy. He made me a flipper with the fake tooth on it that I could take in and out because I was still shooting on ‘The Office.’ I never told [anyone on the show] because they would lose their minds. So I would show up to work on ‘The Office’ with this appliance in my mouth, and it really affected my speech. If you watch those episodes, I sound drunk.”

It all worked out in the end. “The Hangover” was a smash hit, pulling in $468 million worldwide and paving the way for two wildly successful sequels. While those sequels weren’t nearly as beloved – and Galifianakis wishes they never happened — they made a ridiculous amount of money and helped propel all involved to new levels of success. Plus, Helms got a new tooth out of it.
