The Angel's Flight funicular railway cars still run in Los Angeles. The neighborhood in the area has changed quite a bit over the years, though it is still part of downtown Los Angeles.
All the credits except for the title are at the end of the movie, highly unusual for that time.
As Joe Parkson (Robert Ryan) is leaving the car rental lot, the billboard advertising Summer Holiday (1948) with Mickey Rooney is seen; that movie also was a Metro-Goldwyn-Mayer studio movie released in 1948.
The film was entered at the Cannes Film Festival in 1949.
