Janet Leigh could have avoided all that shower nastiness in "Psycho" if she had had access to AltaVista's search engine to find accommodations better than the Bates Motel. That's the message of a spot created by Wieden & Kennedy, Portland, Ore., and tagged "Smart is beautiful." The commercial was intended for use on the Academy Awards show, but was rejected, agency executives said, due to rules covering films nominated for or having won an Oscar. Instead, the ad broke during NCAA March Madness games. Copywriter Bob Moore. Art director: Rob Palmer.
