Tony Rome is a 1967 American neo-noir mystery crime thriller film directed by Gordon Douglas and starring Frank Sinatra in the title role, alongside Jill St. John, Sue Lyon and Gena Rowlands.

The story follows the adventures of Miami private investigator Tony Rome (Sinatra) in his quest to locate a missing diamond pin that belongs to a wealthy heiress.

A sequel, Lady in Cement, was made in 1968, again featuring Sinatra as Tony Rome, and co-starring Raquel Welch and Dan Blocker.

Tony Rome is an ex-cop turned private investigator who lives on a powerboat in Miami, Florida, called ‘Straight Pass’.

[3] Sinatra had originally been considered for the lead role as the tough private eye in Harper (1966), but lost out to Paul Newman.

Though one recent writer sees Sinatra as having created his own version of the private detective, making him a more jaunty and less dour incarnation than Bogart's famous characterizations,[6] the New York Times had been quite critical in 1967 of Sinatra's characterization for precisely that reason: "Evidently Frank Sinatra is trying to go the Humphrey Bogart route....The cryptic Miami Beach gumshoe he plays in this hard-nosed mystery film...is such a conscious or unconscious imitation of Mr. Bogart’s prototypical Sam Spade in the classic ‘The Maltese Falcon’ that you’d guess Mr. Sinatra has been spending a lot of time watching the ‘Late Late Show”....Further, it looks as though the people who wrote and directed this film...have been studying their ‘Late Late Show” too.

Their story...is strangely reminiscent of ‘The Maltese Falcon’ in several essentials and details....All in all, there’s enough demonstration of social vulgarity, degeneracy and crime in the course of this vivid melodrama to satisfy the most lurid tourist taste and it’s put forth with speed, dexterity and a nice running patter of gags....But for all the slickness of it—for all the self-assurance of Mr. Sinatra’s acting style and competence of the others—this thing is still a pat, synthetic job.
