This doesn't show the use (or non-use) of an oxford comma. The rules state that when you are separating a name with a title, or designation, you should use two commas, one before the name and one after the name, or no commas. Your example is wrong, but does not pertain to an oxford comma that separates a list of items.
The list of items are the people. Newt, the 3 star, and the publicist are three different people.
