Did they even ask him? I'm sure he would have loved to reminisce about his role as Biff and Buford. It was his biggest role ever and he was so good in the films! I would have loved to have seen him talk about it. 😞
I think Wilson once remarked that he was pretty tired of the series. He was polite about it but said he wanted to move forward and this was probably fifteen years ago.
that's what i assumed but he's recently done voicework for the videogame. curious.... i think he was under-rated on the films; when you think about it, he played several roles overall (with old, two middle-aged biffs and young biff, as well as and buford, and biff's grandson), and often interacting with them.
i can understand him wanting to move past it, but you would think he's got a lot to be proud of - and a lot of money still to make off it.
When the video game originally came out 5 years ago he didn't want anything to do with it. In the re-released version of the game which came out this year he got in the booth and re-recorded the lines for present Biff who is only a part of the game in the beginning chapter. He didn't re-record any of the ancestors, that's false information.
I think he's mostly joking about that, recently he appeared on local news in Chicago doing some BTTF trivia. But yeah I'm guessing it was a scheduling issue or he wasn't interested in doing another documentary about it.
