Asner is best known for his character Lou Grant, who was first introduced on The Mary Tyler Moore Show in 1970. In 1977, after the series, Asner's character was given his own show, Lou Grant (1977–82). In contrast to the Mary Tyler Moore series, a thirty-minute comedy, the Lou Grant series was an hour-long award-winning drama about journalism. (For his role as Grant, Asner is one of only two actors to win an Emmy Award for a sitcom and a drama for the same role, with the second being Uzo Aduba.) In addition he made appearances as Lou Grant on two other shows: Rhoda and Roseanne. Other television series starring Asner in regular roles include Thunder Alley, The Bronx Zoo and Studio 60 on the Sunset Strip. He also starred in one episode of the western series Dead Man's Gun (1997), as well as portraying art smuggler August March in an episode of the original Hawaii Five-O (1975) and reprised the role in the Hawaii Five-0 (2012) remake. He also appeared as a veteran streetwise officer in an episode of the 1973 version of Police Story.
