About 5 minutes into the film, when Neil first greets Todd in the courtyard & introduces himself as his roommate, Todd says that his brother used to attend the school & Neil says clearly " Oh, you're that HENDERSON". However Todd's surname is not Henderson but Anderson. He is referred to as Anderson throughout the rest of the movie & in the credits.

My hearing may be off, but I have watched that part of the movie over & over & I am convinced I am right.
