Here is the video, and below are a few quotes of interest which I have collected.

Saul Stayed in Milan for a week or so and from what he said when he came back, seemed to get on rather well with the archbishop, who is destined to become the next pope.  When the time came to say goodbye Montini said Saul ought not to leave Italy without having an audience with Pope Pius XII.
   The archbishop arranged it and though Saul’s audience was not a private one, the group was small. He was escorted into the reception room with a gaggle of pious American Catholics. I don’t remember Saul’s saying whether he genuflected to the Holy Ftaher as his companions must have.  The brief audience was concluded with each of his visitors extending a rosary for a papal blessing. Saul, of course had no rosary, but he didn’t want to appear impolite. Digging into his pants pocket he found the latchkey for his apartment in Chicago and held it out in the Pope’s direction. The key was duly blessed and earned a place of didtiction on Saul’s desk a 8 South Michigan. Portrait of Saul Alinsky 173


Two days before the papal election, Alinsky wrote to new IAF Trustee George N. Schuster: "No, I don't know who the next Pope will be, but if it's to be Montini then the drinks will be on me for years to come."9

From 1945 to 1948 Maritain was in Rome serving at General de Gaulle’s request as France’s ambassador to the Vatican. Pope Pius XII apparently took inspiration from Maritain philosophical work, as would monsignor Montini who would come to regard Maritian as his master…In 1948 Maritain was head of the Paris delegation and served as president of the UNESCO general conference in Mexico City.

The internship with Alinsky had an enormous impact on the career of this young cleric. It was financed by Cardinal Stritch who gave Alinsky $40,000 a year for a three-year study of Chicago's racially troubled neighborhoods. (that’s in 1954) (73) Finks, The Radical Vision 111.

Alinsky made inroads into the Chicago Catholic hierarchy through his close friend Bishop Sheil auxiliary bishop of Chicago. Bishop Sheil was the only Catholic Bishop to publically denounce Senator Joe MaCarthy

In April 1954 the bishop appeared before more than two thousand members of the United Automobile Workers in Chicago’s Civic Opera House to denounce the “phony anti-communism” practiced by the junior senator from Wisconsin.” I am almost sure Saul arranged (author) Sheil’s appearance. I know that he arranged for massive media coverage. The speech was one of the first of an avalanche of large boulders which did on “Tailgunner Joe” as he was known to his admirers.

Sheil also attacked the radio priest father charles Coughlin.

Alinski’s feud with McIntyre

“Alinski anticipated parish support in Los Angeles, but Fred Ross advised Alinsky that “while Mexican Americans came out of Catholic traditions, an organizer could not expect much leadership from the young priests as Alinsky had enjoyed in Chicago.” Cardinal McIntyre, who determined the activities of all the parishes in the loss angeles archdiocese, recognized the new aspirations of returning veterans, but he discouraged –some suggest he even persecuted- priests and nuns who engaged in community activism. Instead, Cardinal McIntyre promoted community school buildings and “Americanization” programs.”

Pius XII was extremely ill in 1958, and it doesn't seem that Alinski got any special treatment, being admitted with several others on a formal visit.

Saying a pope was a plant is not something you should do loosely.

The friendship with the Frenchman, which began in the early 1940s and continued through Alinsky’s death, was in von Hoffman’s view a “wider and deeper relationship than with any other Catholic,” despite his closeness to O’Grady and Egan. It was as a favor to Maritain that Alinsky met and advised Cardinal Giovanni Montini (the future Pope Paul VI) over his concerns about the growing hegemony of the Communist Party in Northern Italy’s red belt. On that same trip, the agnostic Jєωιѕн radical had an audience with Pope Pius XII.
