So what do I need to do for my addition to be deemed legitimate?
The first complaint is that, "Sources do not provide complete link with Erdos." I provide a link to Frank Harary's list of publications that shows K. Hodges as a co-author on a paper, and Harary's Wikipedia entry states that Harary has an Erdos number of 1. This is a complete link.
The second complaint is, "No evidence that he is the one of three K. Hodges on IMDb." I'm not sure how to provide this. You could look at these two pictures and decide if they're the same person:

What else would be sufficient?
