The kegs at the graduation party were filled with real beer. According to the directors, in the scene in which Cooper is thrown behind Scotty after the hot tub incident, Jacob Pitts is quite inebriated.
Matt Damon originally did the cameo as the lead singer of the band Scotty Doesn't Know due to the fact that he went to college with Alec Shaffer, Jeff Berg and Dave Mandell. He was in Prague shooting The Brothers Grimm when Alec, Dave and Jeff asked him if would play the part. Due to the fact he was required to wear a wig in his part in The Brothers Grimm, he spontaneously shaved his head for the EuroTrip cameo.
While filming the nude beach scene, Jacob Pitts would not put his shorts back on, because he was enjoying how uncomfortable it made everyone else.
Ironically, on the Unrated DVD cover art it shows Michelle Trachtenberg taking her bikini off. She's actually the only main character in the movie who doesn't go naked. However, in the outtakes during the credits, there is a brief shot of her being topless (though seen from behind). This was part of a longer deleted scene where she unsuccessfully tries to hitch a ride by flashing truck drivers.
The original text of the email Scotty receives Mieke actually says: Lieber Scott, Ich war ein sehr trauriges Mädchen, als ich hörte, dass deine Freundin Fiona dir den Laufpass gab. Aber vielleicht ist es so zum Besten. Ich war jedenfalls sehr froh darüber! Ich muss für nächstes Jahr eine grosse Entscheidung treffen. Und da dachte ich, da du ja jetzt keine Freundin mehr hast, könnte ich in die Vereinigten Staaten kommen und wir könnten uns besser kennenlernen. Vielleicht könnten wir ein Treffen arrangieren. Bis Bald, Mieke. Translated, this says: Dear Scott, I was a very sad girl when I heared that your girlfriend Fiona dumped you. But maybe it is for the best. I was glad about it, anyway! I must make a big decision about the next year. And I thought, that since you don't have a girlfriend anymore, that I could come to the United States and we could become better acquainted. Maybe we can arrange a meeting. Until soon, Mieke.
