Marty (1955)

Stuck as the last of six children at home with an overbearing Italian mother, the only child still unmarried, 34 year old socially awkward Bronx butcher Marty faces middle age with no prospects of marriage, and he faces permanent bachelorhood. But when he is goaded by his mother into going to the Stardust Ballroom one Saturday night, Marty unexpectedly meets Clara, a lonely teacher. Suddenly, Marty's future seems bright.
