The UCLA Hammer Museum in Los Angeles has been mostly finished for a decade. When the building opened in 1990, a design for a theater was incorporated and roughed out, but never fully built. The Hammer Museum has now received a $5 million gift from the widow of director Billy Wilder, with the money to be used to complete the theater project. “The Wilder donation gives a much-needed boost to the museum’s fund-raising campaign for its planned $26.5-million renovation.”
