Appointment with Danger is a 1950 American crime film noir starring Alan Ladd and Phyllis Calvert, supported by Paul Stewart, Jan Sterling, and Jack Webb.

[3] Produced and distributed by Paramount Pictures, the drama was directed by Lewis Allen and written by Richard L. Breen and Warren Duff.

At the Hotel Compton in Gary, Indiana, U.S. postal inspector Harry Gruber is murdered by two men, Joe Regas and George Soderquist.

Meanwhile, Regas, whom Mary does not recognize, sees her and telephones Earl Boettiger, the head of the gang and owner of the Hotel Compton, warning him to hide Soderquist.

[11] The film features Jack Webb and Harry Morgan as villains, later famously paired as Los Angeles police detectives on the Dragnet television show.

He wrote, "[I]t's fairly obvious that it's all familiar stuff to our hero, for he evinces as much emotion over these muscular goings-on as a postal clerk counting air mail stamps.

But he is fortunate in having a vehicle, which is basically a cops-and-robbers tale, tautly written by scenarists Richard Breen and Warren Duff, who also have injected humor in the modern idiom into their dialogue.

As a result, Appointment With Danger lives up to its title as Ladd, checking on the murder of another postal inspector in Gary, Ind., finds a visiting nun who saw the criminals.

"[13] Variety gave the film a positive review, writing, "Ladd is right at home as the tightlipped, tough inspector assigned to the case.

There is a neat contrasting byplay in the nun character done by Phyllis Calvert as co-star, which adds an offbeat note to the meller plot.
