The University of Michigan Board of Regents approved the design Thursday of the Arthur Miller Theatre, as a tribute to one of its most famous graduates.The 250-seat theater will be part of the Walgreen Drama Center, the new home of the departments of theater, drama and musical theater on U-M\'s north campus. It was proposed in 1997 and will open in 2007. Miller, the Pulitzer Prize-winning playwright who died last month at the age of 89, had resisted other attempts to name a theater in his honor. But when former U-M President Lee Bollinger approached him in 1997, Miller responded with a simple postcard. \"The theater is a lovely idea,\" Miller wrote. \"I\'ve resisted similar proposals from others but it seems right for Ann Arbor.\" It is believed to be the only theater in the world named for Miller, according to U-M officials.
