When the President decides to pass through the small town of Suddenly on route to a fishing trip, the town's police and chief officials rise to meet the challenge of assuring his protection as there have been rumors of an assassination attempt.

The hired guns meanwhile make plans of their own. They cleverly trick their way into the home of the best house in town from which to try and carry out their assassination plot - the house of Pop Benson, respected citizen with an house upon an hill that overlooks the President's planned arrival destination. Now only an handful of hostages stand between the President and doom...can they in some way warn him in time?

Frank Sinatra steals the show here as the ruthless criminal mastermind behind the want-to-be assassins - a man named John Baron. He is downright brutal and nasty in the role--an utterly detestable villain who does remind us the it was the army that created him and made him into a killer or maybe deep down, it's just that he was always a killer at heart. An outstanding multi-dimensional performance from Sinatra.

Sterling Hayden meanwhile plays the idealistic police sheriff Tod Shaw, who believes in America and the American way and supports unquestioningly the system and will do whatever it takes to preserve the America he believes is right and just. He too served in the military to protect rights and freedoms and now carries on the good fight as Suddenly's sheriff. An interesting contrast of two extremes with the pacifist minded Ellen Benson (played here by Nancy Gates), her becoming a widow after her husband got killed in the war, finally forced to take a stand at the film's climax.

Daring for its time, this film deals with surprisingly intense subject matter for the early 1950s. Quite good.

The movie focuses US President protected by Secret Service (Willis Bouchey as Chief agent) who passes through a small and peaceable town called Suddenly where only the sheriff (Sterling Hayden) executes the law . One house inhabited by a grandfather (James Gleason) , a widow (Nancy Gates) and son is ideal place for a criminal scheme by means of an ambush , designed and pulled off by ominous murderers commanded by a ruthless psycho assassin (Frank Sinatra).

The film has got emotion , strain , suspense , thriller and although is mostly developed on interior scenarios , it doesn't make boring neither tiring . Release was withdrawn from circulation for the Dallas assassination (1963) because of the events are pretty similar . Frank Sinatra (JFK's friend) as producer ordered the retaining copies and the movie was forgotten , however long time later was issued in video market and obtained a lot of success . Frank Sinatra's interpretation is top-notch as the cruel and brutal killer , his acting is magnificent , he's the best . Attractive Nancy Gates is the pacifist widow who hates the guns and embittered for her husband's death during WWII . Sterling Hayden interprets properly a kind and valiant police believer of the ¨American way of life¨ . James Gleason as stiff and rigid veteran is very fine . Atmospheric cinematography and agreeable musical score by David Raksin (author of Laura's score) . The motion picture was well directed by Lewis Allen (he directed some noir classic films). Rating : Interesting , worthwhile seeing and it will appeal to Frank Sinatra fans.

I'm at a loss to explain why Frank Sinatra chose this particular project in the wake of all the acclaim he got for From Here to Eternity. Without his presence in the film, Suddenly with its length of 75 minutes on my VHS version would be a B film, even with Sterling Hayden starring in it as the sheriff. My guess is that Sinatra wanted to expand and test himself as an actor, something he did less and less of in the following decade.

The President of the United States is coming to the small town of Suddenly where he will leave the train he's traveling on and proceed by motorcade to a vacation in the Sierras. The Secret Service has come to town to do their usual thing in protecting the Chief Executive.

But three contract killers headed by Frank Sinatra are in town to kill the president. We're never told exactly who is paying for this contract, but the inference is that it is our Cold War enemies. Through a combination of circumstances the sheriff is wounded and the head of Secret Service detail, Willis Bouchey, is killed. And the killers are holed up in Nancy Gates's house with her, her father-in-law James Gleason, and child Kim Charney and the wounded Hayden.

Most of the film is taken up with the wait for the train to arrive where a lot of souls are bared open, including Sinatra's. It's the one and only time that Francis Albert ever essayed the role of an out and out villain. He does it well, but I suspect he didn't want to push it with his public too much, so he never did anyone as evil as this again.

Of course history tells us that the president named Eisenhower at the time never was an assassin's target so we know Sinatra's efforts will fail. However it's rather ingenious as to how it does fail.

I think more than fans of old Blue Eyes will like Suddenly.
