The movie's finale wrestling match runs for half an hour, around a quarter of the picture's running time. The big fight was staged at the MGM Grand Hotel in Reno, Nevada. Not surprisingly, the studio making the picture was Metro-Goldwyn-Mayer (MGM).
Although the film was a box office flop in the USA, it did reasonably well abroad, enough to warrant talk of a sequel that never came to fruition. This was largely due to the death of Robert Aldrich. The sequel was planned to be predominantly set and filmed in Japan.
The picture's American title was changed from "All The Marbles" to "The California Dolls" for release in foreign markets because the phrase "All The Marbles" is an American idiom and not well known outside of the USA.
The legendary woman wrestler Mildred Burke and two of her pupils (who appear in the first match while the credits roll) trained the two female leads for several weeks. After intensive work, Laurene Landon and Vicki Frederick actually performed the wrestling action without doubles.
Breakthrough film role and first major film role of actress Laurene Landon. Landon has said that although the movie did not perform well in the USA, it did much better at the box-office in foreign territories.
In decided contrast with how professional wrestling is usually portrayed, the film promotes the idea of pro wrestling as being real, as spelled out by the Toledo Tigers' manager after the Dolls' first match with them. As he puts it, "Nobody's supposed to win!"
