In the real world, the 1951 New York baseball Giants won the National league pennant in a three-game playoff over the Brooklyn Dodgers with the help of some "angels" of their own. In the bottom of the ninth inning of the third game, the Giants won the game 5-4 on a three-run homer. The dramatic hit by Bobby Thomson was dubbed "the shot heard round the world" and was the culmination of "The Miracle of Coogan's Bluff" in which the Giants won 37 of their last 44 games to make up 13½ games on the Dodgers to force that now most famous playoff series.
The uncredited hat check girl was played by Barbara Billingsley, future TV mother as June Cleaver on Leave It to Beaver (1957) and the jive-talking passenger and interpreter in Airplane! (1980).
Bing Crosby appeared in the film because, at the time, he was a partial owner (approximately 15%) of the Pittsburgh Pirates.
One of the wrestlers seen on the new television is Tor Johnson, who is best known for his role in Plan 9 from Outer Space (1957).
