and perform effortlessly, Tracy's acquaintances said that he would carefully prepare for each role in private. Joseph L. Mankiewicz lived with him during the production of Test Pilot, and recounted that Tracy would lock himself in his bedroom "working extremely hard" each night. Many co-workers commented on his strong work ethic and professionalism. However, he did not like to rehearse and would quickly lose his "effectiveness" after shooting two or three takes of the same scene. Kanin described him as "an instinctive player, who trusted the moment of creation". Tracy's close friend Chester Erskine pinpointed his acting style as one of "selection", stating that he strove to give as little as was needed to be effective and reached "a minimum to make the maximum". Tracy disliked being asked about his technique or what advice he would give to others. He often belittled the profession of acting, once saying to Kanin, "Why do actors think they're so goddamn important? They're not. Acting is not an important job in the scheme of things. Plumbing is." He was also humble about his abilities, telling a journalist, "It's just that I try no tricks. No profile. No 'great lover' act ... I just project myself as I am—plain, trying to be honest." He was known to have enjoyed the quip once made by Alfred Lunt, "The art of acting is: learn your lines and don't bump into the furniture!" Hepburn, in an interview six years after Tracy's death, suggested that Tracy wished he had held a different profession. Assessment and legacy In the 21st century, Tracy is best known to general audiences for his association with Katharine Hepburn. He continues to receive praise from film scholars: critic Leonard Maltin calls Tracy "one of the 20th century's finest actors", while film historian Jeanine Basinger describes his career as a "golden record of movie achievement". Charles Matthews, writing for The Washington Post, argues that "Tracy deserves to be remembered for himself, as a master of acting technique". An award for excellence in film acting is bestowed in Tracy's name at the University of California, Los Angeles. Past recipients of the UCLA Spencer Tracy Award include James Stewart, Michael Douglas, Denzel Washington, Tom Hanks, Anthony Hopkins, Kirk Douglas and Morgan Freeman. A 1986 PBS documentary titled The Spencer Tracy Legacy was hosted by Hepburn. It includes clips from Tracy's films, and behind-the-scenes archival footage and home movies
