(AP) — The man in the gray T-shirt and blue ball cap sported a name tag that said “M. Damon” and created a stir as he toured the University of Nebraska-Lincoln campus.

It was megastar movie actor Matt Damon, who first gained movie fame as a troubled math genius working as a janitor at the Massachusetts Institute of Technology.

Damon told well-wishers that he was in Lincoln on Wednesday to attend New Student Enrollment Day with his nephew, who’d enrolled as a freshman and will start classes there in the coming fall semester.

Damon and university officials declined to give the new student’s name.

Damon said he “basically bought out” the University Bookstore while stocking up on Nebraska Cornhusker gear for his children.
