I just got through watching the original version of the movie The Producers. Genius, pure genius. Gene Wilder gives one of his best performances and launches his comedic career. Zero Mostel is masterful as you would expect. There are some surprises too, the best being Christopher Hewitt (best known in the US as Mr. Belvedere) as the director.
Now, I love Nathan Lane, Matthew Broderick and Wil Ferrell. (and Uma Thurman for that matter, although Lee Meredith was better in the original) But there is no way the new version can be as good as the original. In fact, from the clips I have seen, it's not.
I really hope Mel doesn't decide to re-make Blazing Saddles or Young Frankenstein next.
