Jeremy hosts and narrates portions of the featurette, which provides an overview of the film's production and restoration. Among the subjects covered, of course, was the dubbing of Audrey Hepburn's singing voice by Marni Nixon. Jeremy also laments that his songs were dubbed as well, by a singer named Bill Shirley: "When I arrived on the set, I found to my horror that someone else had sung my song." 

The featurette offers some scenes with Hepburn singing, but alas, there is no footage of Jeremy's real voice.

Roger Ebert review of My Fair Lady: 

The story is well-known. Eliza Doolittle (Audrey Hepburn) is first insulted for her accent by the famous linguist Henry Higgins (Rex Harrison), and then offers him a shilling a lesson to teach her to speak like a lady. Higgins and his friend Col. Pickering (Wilfred Hyde-White) make a bet on the outcome, and Higgins transforms Eliza in six months. The supporting characters ... include Eliza's father (Stanley Holloway) and Henry's mother (Gladys Cooper). Only poor lovestruck Freddy (Jeremy Brett) doesn't have a brain in his head: Shaw, impatient with romantic plotting, sticks him in when he needs him and then drops him without another word.

ReelViews review: 

The film's origins go back to George Bernard Shaw's Pygmalion (1912), which was subsequently adapted into a Broadway musical by the incomparable team of Alan Jay Lerner and Frederick Lowe (Gigi, Camelot). The play debuted in 1956. It took seven years before the Warner Brothers-produced motion picture adaptation, with George Cukor at the helm, began filming. There was controversy even before the first frame was committed to celluloid. While both Rex Harrison and Stanley Holloway were brought on board to re-create the roles they had essayed on the stage, the part of Eliza Doolittle, played in the Broadway production by a then little-known Julie Andrews, was given to Audrey Hepburn. In a richly ironic twist, Andrews won the Best Actress Award that year for Mary Poppins, while Hepburn was snubbed by the Academy.

Greatest Films site has an extremely detailed plot description, including this note: The originalPygmalion had an ambiguous ending. Higgins' last line was, "Nonsense - she's going to marry Freddie. Ha ha ha!" An additional prose ending added by George Bernard Shaw left no doubt that Eliza did indeed marry Freddie. 

The Brettish Empire, among many great anecdotes, says that Jeremy reportedly beat out 40 other "shiny young Englishmen" for the role of Freddie.

A real behind-the-scenes tragedy, recounted in the book, Audrey Hepburn, by Barry Paris: 

"We were filming the part where Eliza returns to Covent Garden with Freddy," recalled Jeremy Brett, when someone rushed up to their carriage with word that President John F. Kennedy had been murdered. "We sat in the car with the blinds down, holding each other and crying on stage seven at Warner Brothers." 

Another making-of moment was reported in the New York Times: The collision between Freddy and Eliza in the opening scene -- when he bumps into her in Covent Garden in the rain and scatters her flowers -- had to be repeated for more than two hours before director Cukor felt it was right.

For the gala "repremiere" of the movie, held in New York on Sept. 19, 1994, Jeremy Brett was one of the very few surviving costars in attendance.
