You're My Everything (1949)

In 1924, stage-struck Boston blueblood Hannah Adams picks up musical star Tim O'Connor and takes him home for dinner. One thing leads to another, and when Tim's show rolls on to Chicago a new Mrs. O'Connor comes along as incompetent chorus girl. Hollywood beckons, and we follow the star careers of the O'Connor family in silents and talkies. Includes good imitation "silents" with classic cameo by Buster Keaton.
