I was going by the poster but now I notice that the year 1955 is being quoted. So I'm confused now as well! I expect Twilight Time will let us know pretty quickly.
Sooner or later I'll have all four of these films on Blu-ray disc. Right now I'm particularly interested in My Gal Sal with both Rita Hayworth and Carole Landis. The DVD-R is awful so I'm hoping Fox will produce one of their miracles.
