"Suddenly" (1954) Ol' Blue Eyes solidified himself as a powerful dramatic actor the following year in this gritty, low-budget thriller in which he plays the leader of a group of gunmen hired to assassinate the president while on a train stop at a small town called Suddenly. Though some of the subplot is hokey, Sinatra is electrifying. Newsweek described him as "one of the most repellent killers in American screen history." Supposedly, this was the film that Lee Harvey Oswald saw just a few days before he shot President Kennedy. When Sinatra, who was a close friend of JFK, learned this, he insisted the film be withdrawn from circulation.
