The only actors to appear in all three films of the Dorm Daze trilogy are: James DeBello (Cliff), Tony Denman (Newmar), Jennifer Lyons (Lynne), Patrick Cavanaugh (Pete), Paul Hansen Kim (Wang), Patrick Casey (Mike) and Josh Miller (Brady).
During the campus orientation, Pete asks if anyone knows what famous campus building Eugene O'Neill died in. O'Neill did in fact die in a campus building: room 401 of Shelton Hall, a dormitory in Boston University (which had been a hotel at the time of Eugene's death).
When Foosball and Styles are talking after Booker goes to call Rachel, Foosball is smoking a cigarette. In one shot his hand is by his side, while in the next, his hand is by his face as he puffs the cigarette.
