Contrary to rumor, a young Fidel Castro does not appear as an extra. The rumor grew from two sources: his yearbook, in which teachers noted that he was "somewhat of an actor," and a 1943 interview where Xavier Cugat cryptically referred to one of his dancers becoming "a South American general." In his 1948, Cugat references being an acquaintance of Huber Benitez, who later became a General and supporter of Fulgencio Batista, whom Castro overthrew in 1959.
This was seventeen year-old Jane Powell's first film for MGM under her new contract with the studio.
The grand piano seen being played by José Iturbi in his home when Christine is singing "I Think of You" is called a "giraffe" piano, an early design from the 1800's. It's a grand piano essentially set on end with its pointed tail in the air, producing the asymmetrical shape. It might be described as folding a grand piano beyond the keyboard 45 degrees so it's pointing towards the ceiling. Placing shelves in the upper part of the case to the right of the strings yielded the tall rectangular "cabinet piano." Because the lower end of the strings, which ran nearly vertically, was about at the level of the keyboard, all such instruments were very tall. Although there were attempts to construct lower instruments by, in effect, positioning a square piano on its side, the American builder John Isaac Hawkins made the first truly successful low uprights in 1800 by placing the lower end of the strings near floor level.

At this time, color broadcasting was in its infancy, limited to only a small number of high rated programs, primarily on NBC and NBC affiliated stations, so these film showings were all still in B&W. Viewers were not offered the opportunity to see these films in their original Technicolor until several years later.
From Wikipedia:
The Father Complex in psychology is a complex-a group of unconscious associations, or strong unconscious impulses-which specifically pertains to the image or archetype of the father. These impulses may be either positive (admiring and seeking out older father figures) or negative (distrusting or fearful).
