It is a very good film. In the last couple of months I reviewed Topsy Turvy for my column - it was the 25th anniversary of the movies released, and it remains one of my favorite movies ever made. I am a huge Gilbert and Sullivan fan (almost since the womb) and I remember seeing Topsy-Turvy in the theaters. Even at 20 I knew Leigh's traditioal way of making films, and I figured he must have written a script. I was astonished to learn not long after that he wrote Topsy-Turvy the same way he did Secrets and Lies and Happy-Go-Lucky.
If you are a Gilbert and Sullivan fan, you will love this film perhaps more than the average movie-goer. I'm the kind of person who understood the inside baseball with so many of the lines in this film. Leigh's films are divisive - I've seen five or six and it is only Secrets and Lies and Topsy Turvy that I unabashedly love. I will never understand, however, why Hawkins recieved every award in the book for her work here - including the Golden Globe - but not even a nomination from the Academy.
BTW, Mike Leigh has been nominated for Best Original Screenplay five times. Given how his creative process, do you think he deserves sole credit? Curious.
