"When Crispin decided he wanted to sue Universal, the cast and the production team, he contacted me and was very whiney about how badly they treated him on the first film. The producers belittled him and made him cry in front of extras on the first shoot, cut his hair without his approval, and how much he had been "done wrong" because they were going to pay him twice scale for the use of the short clips they used of him from the first film, inserted into my work on the second.
I did see that he was being cheated, especially because they used his likeness (Universal's argument was that they were using "George's likeness"), and after Crispin got his $760,000 out-of-court settlement (before it went to trial), using much of our conversation as fuel for his case, Universal blacklisted me and never used me on a TV show or film again, and Crispin has never taken my calls nor spoken to me since.
I took it very hard that production tried to keep my work a secret, kept me from promoting my work on the films publicly, and I had a nervous breakdown when I heard of the blacklisting by Universal. To top it all, hardcore Back to the Future and Crispin fans have written "hate Jeffrey Weissman" postings in public forums, which are pretty painful. Ahh, showbiz."
