Ann Blyth attempts to ride “Irish,” her Paramount transportation, during production of “The Buster Keaton Story,” the 1957 biopic with Donald O’Connor as the iconic Silent Screen comedy great. Blyth plays a fictional Famous Studios casting director who falls for the sad-eyed star.

Here’s the snipe: HOBBLED HEROINE — Ann Blyth finds that the long, tight hobble skirts of the 1917 period in Paramount’s VistaVision filing of “The Buster Keaton Story” don’t mix too well with the bicycle the studio assigns her during the shooting schedule. It’s just not possible to lift one’s pretty ankle onto the pedals when there’s so much hardware in the way, Ann finds.
