In 1951, the year of this film's release, the Pirates were in a very long dry spell, 9 years prior to their first World Series appearance since 1927. The obvious set-up : "Heaven help the Pirates".
I saw this picture as an adolescent during its theatrical release, and 5 times recently. In addition to perfect casting of Paul Douglas, then in his prime - having recently filmed "Panic in the Streets" , the supporting cast is superb, notably Spring Byington and Ellen Corby as Sisters and Janet Leigh is a very credible love interest .Donna Corcoran is a wonderful orphan.
What I admire almost as much as the acting, premise and writing is the director's use of actual Pittsburgh locations, although there was no imperative to do so. Included: the King Edward Apartments, Forbes Field, PCC trolley cars, Bigelow Boulevard, Checker cabs. As a former Pittsburgher, I can attest to the authenticity of these elements.
A sentimental favorite of mine, but not just for Pittsburgh fans.
