William Powell was great in The Thin Man and Life with Father but my favorite is My Man Godfrey.

Powell received an Academy Award nomination for The Thin Man (1934) and later starred in the Best Picture winner for 1936, The Great Ziegfeld (1936). Powell could play any role with authority, whether in a comedy, thriller, or drama. He received his second Academy Award nomination for My Man Godfrey (1936) and was on top of the world until 1937, when he made his first picture with Jean Harlow, Reckless (1935). The two clicked, off-screen as well as on-screen, and shortly became engaged. One day, while Powell was filming Double Wedding (1937) on one MGM sound stage, Harlow became ill on another. She was finally taken to the hospital, where she died. Her death greatly upset both Powell and Myrna Loy, and he took six weeks off from making the movie to deal with his sorrow. After that he traveled, not making another MGM film for a year. He eventually did five sequels to "The Thin Man," the last one in 1947. He also received his third Academy Award nomination for his work in Life with Father (1947).
Godfrey: Tommy, there's a very peculiar mental process called thinking - you wouldn't know much about that - but when I was living here I did a lot of it.
