Rogen and Goldberg may have spent years writing Superbad, but they weren’t precious about the actors sticking to the script.
Hill was “constantly” improvising, Stone told E!. “I could not keep a straight face. There were quite a few moments that have been cut out and I think—you know, I’m maybe taking the blame on myself that I laughed in the middle of every take. I tried to learn as time went on, but it got harder for some reason because it got funnier and funnier as we sunk into it.”
In fact, Hill improvised the affectionate “boop, boop, boop” that Seth bounced off of a legitimately surprised Evan’s nose when the bestest buds are bromantically admitting how much they love each other.
Slater busting out Van Halen‘s “Panama” while doing donuts in the squad car was also Hader’s in-the-moment creation. “Then Judd got mad at me,” the Barry star told The Ringer, mimicking Apatow telling him, “‘Do you know how much “Panama” costs?!'”
As it turned out, the rights to use “Panama” alone “cost nearly as much as all of the songs in Adventureland,” director Mottola told The New York Times in 2009, referring to his smaller-budgeted follow-up to Superbad.
