I’ve seen 3 recently:
The Picture of Dorian Gray - shots of the painting of young-and-pretty Dorian and old-and-dissipated Dorian are in color.
Portrait of Jennie - like Dorian Gray, Jennie’s portrait at the very end of this film is shot in full color. The storm sequence is also tinted green, and the morning after the storm is tinted pale red.
The Secret Garden - When the children go into the garden, the film switches to color.
Seeing these so close together made me wonder: How many films are there like this? Can anyone name any others? (No, not Wizard of Oz–I’m thinking of short segments in otherwise black-and-white films.) All three of the above were made in the late '40’s; was this sort of thing a fad during the post-war era, when Technicolor was too expensive for all-but-the-most-special movies, but film-makers still wanted to highlight certain shots or give their films that little extra kick? Any ideas?
