1955. Early productions included some of the classical works of Shakespeare: Hamlet, Richard II, The Taming of the Shrew, Macbeth, Twelfth Night, and The Tempest. Biographical subjects were very eclectic, ranging from Florence Nightingale to Father Flanagan to Joan of Arc. Popular Broadway plays such as Harvey, Dial M for Murder, and Kiss Me, Kate were made available to a mass audience, most of them with casts that had not appeared in the film versions released to theatres. In a few cases, the actors repeated their original Broadway roles. Actors such as Richard Burton, Alfred Lunt, Lynn Fontanne, Maurice Evans, Katharine Cornell, Julie Harris, Laurence Olivier and Peter Ustinov all made what were then extremely rare television appearances in these plays. Two different productions of Hamlet have been broadcast on the Hallmark Hall of Fame, one featuring Maurice Evans (1953) and the other a British one featuring Richard Chamberlain (1970). Neither version was more than two hours long. Evans and actress Judith Anderson performed their famous stage Macbeth on the Hallmark Hall of Fame on two separate occasions, each time with a different supporting cast. The first version in 1954 was telecast live from NBC's Brooklyn color studio while the second in 1960 was filmed on location in Scotland and released to movie theaters in Europe after its American telecast. The Richard Chamberlain version of Hamlet, which was also telecast in Britain on ITV Sunday Night Theatre, won five Emmys when telecast on the Hallmark Hall of Fame, out of a total of thirteen nominations. It may have set a record for the most-nominated Shakespeare production to ever be televised. In 1955, Hallmark Hall of Fame switched its format to a special series seen only four to eight times a year around greeting card holidays and in 90-minute or 120-minute length. Starting in 1970, the frequency dropped to two to three times a year. The source material were plays and novel from major authors and were produced with stage actors and actresses. Hamlet, Macbeth and the other Shakespeare plays presented on Hallmark Hall of Fame were cut (sometimes drastically) to fit the time limits of a standard film or of the Hallmark Hall of Fame itself, which during the 1950s, '60s and '70s never ran longer than two hours and frequently even less. It was left to National Educational Television (NET) and Public Broadcasting Service (PBS) to be the pioneers
