Television writer Arnold Peyser, part of the husband-wife team that scripted such shows as ``The Brady Bunch'' and ``My Three Sons,'' died Sunday of cancer. They collaborated on scripts for ``The Dick Van Dyke Show,'' ``Love, American Style,'' Disney's ``The Wonderful World of Color'' and the Alcoa, Goodyear and General Electric theater series. The couple also wrote the screenplay for the 1969 Elvis Presley movie ``The Trouble With Girls.''
