Appointment with Danger (1950)
This 1950 film noir stars Alan Ladd, Phyllis Calvert, and Paul Stewart. The plot is pretty hokey and the first few minutes of the film seem like an infomercial for the U.S. Post Office, but this film gets very entertaining very fast.
Two thugs murder a U.S. Postal Inspector and then dump his body. A nun (Calvert) inadvertently sees the thugs. Al Goddard (Ladd), another U.S. Postal Inspector, investigates the murder by first locating the nun. After he finds her, he tracks down one of the killers and subsequently infiltrates the killers' gang.
There is plenty of snappy dialogue and a lot of funny lines. Goddard is a hard and determined man and is accused by a fellow officer of being inhuman and without feelings. The fellow officer says to Goddard, "You don't know what a love affair is." Goddard replies, "It's what goes on between a man and a .45 that won't jam."
Ironically, this film stars Jack Webb and Harry Morgan as the killers. Just two years later, Webb would begin starring on television as Detective Joe Friday on Dragnet. And in the late 1960s, Webb would team with Morgan again when Dragnet returned to television – and they dressed in just the same style as they did in the 1950 film.
I saw this film for the first time last summer and I liked it so much that I saw it again this winter. If you like old movies, this is a good one, and if you don't, you may like it anyhow.
