Greg Heffley (headshot)

Dieter Muller was a German exchange student and the very first victim to the Cheese Touch; a moldy slice of swiss cheese laying on the blacktop of the playground. Upon touching the cheese, a kid named Darren Walsh (played by Harrison Houde) initiated the Cheese Touch. Anyone who touches the cheese becomes an outcast since no one will want to get touched by them until they pass on the cheese touch by touching someone else. He only appears in the movie, replacing the role of Abe Hall of the book sieries.
