Oz, however, was one of Jims closest friends and should have been present. According to Chris Klein, he was never invited to reprise his role in American Wedding, which is odd. Its not often a main character is so obviously snubbed from a sequel only to be brought back later on in the series.
One may also ask, why did Oz not appear in American Wedding? Chris Klein stated in an interview with Huffpost that Oz, Vicky and Heather were not considered for the movie and that he didnt refuse to reprise his role as many believe. In a deleted scene Jim explains Ozs absence from the wedding saying he was still in Spain with Heather another absent character.
Keeping this in view, who plays Ozs girlfriend in American Reunion?
Katrina Bowden
