I won't address the plot, which I believe is superb, as this has been done amply by others, but rather the DVD edition. The print is vastly superior to the video release which had a jump in it during the moment when Jill Lynn (Grable) makes her way over the rooftops of New York to evade the police, who mean to let her escape so they can follow her to Frankie Christopher (Mature), the man she loves. Given that this is one of the scenes I remember best, that spoiled it for me. There was jump in another place, if memory serves, but all these are gone.
Extras include a cut scene where Grable sings 'Daddy' to a customer at the store before going off to take her sister to the station (in fact Jill is dead). This is fascinating, as it presents a very different film. I'm glad the scene was cut, as it would have totally spoiled the film, a comic, musical-type fragment in a great noir film, which keeps up the suspense throughout. That said, it's always a joy to see and hear Betty Grable sing.
Also included are images of the original publicity and titles. At first the film was to be called 'Hot Spot', but they changed the name to that of the story on which it was based, fearing that 'Hot Spot' might be mistaken for a musical. The changes reveal a film that was tightened up, Betty Grable's musical supports (as far as I'm aware, she sang in every other 'serious' film she made) removed. Yet she's a real revelation. She could do drama without singing, dancing, or showing off her legs (she hated the lido scene, which should also have been cut as detracting from the picture).
All in all, this is an excellent edition of an excellent film. If you bought the video and liked it, even with the faults, buy this. It is superior to it in every way. You will not be disappointed.
