Yes, very much so, but it's more a minor work, I think, rather like Filming Othello.
The interview with Burt Reynolds is very long and focuses much more on Reynolds than Welles - the audience were asking questions and most of them were not about anything Welles had done. The interview with Jim Henson and Frank Oz is okay. There's a montage with the Muppets which is strange rather than funny. And there's a couple magic tricks with Angie Dickinson, one of which was reused in the Munich restoration of the Magic Show.
I didn't think the show was as successful as it might have been, but I enjoyed it and consider it worth owning. I think chronologically it was Welles' last completed project.
