Book excerpt: Did you know that, according to director Chris Columbus, Robin Williams improvised so much during the filming of Mrs. Doubtfire that the studio had enough footage to release PG, PG-13, R, and NC-17 versions of the movie? Or that Robin ad-libbed all his lines in Good Morning, Vietnam because the DJ the movie was based on didn’t really do comedy during his shows? Robin Williams, American Master looks at Robin’s seventy movies, from his earliest appearance in Can I Do It…’Til I Need Glasses? to his final posthumous voice-only appearance in Absolutely Anything. Each film is discussed in detail, with special emphasis on Robin’s performances and how they exist in the context of his entire body of work. Robin Williams, American Master is the perfect tour guide through Robin’s epic collection of cinematic genius.
