The musical adaptation of his film The Producers to the Broadway stage broke the Tony record with 12 wins, a record that had previously been held for 37 years by Hello, Dolly! at 10 wins. This success led to a big-screen version of the Broadway adaptation/remake with actors Matthew Broderick, Nathan Lane, Gary Beach, and Roger Bart reprising their stage roles, in addition to new cast members Uma Thurman and Will Ferrell in 2005. In early April 2006, Brooks began composing the score to a Broadway musical adaptation of Young Frankenstein, which he says is "perhaps the best movie [he] ever made." The world premiere was performed at Seattle's Paramount Theater, between August 7, 2007, and September 1, 2007, after which it opened on Broadway at the former Lyric Theater (then the Hilton Theatre), New York, on October 11, 2007. It earned mixed reviews from the critics.
Brooks won a Hugo Award and a Nebula Award for Young Frankenstein. In a 2005 poll by Channel 4 to find The Comedian's Comedian, he was voted No. 50 of the top 50 comedy acts ever by fellow comedians and comedy insiders.
