Unlike some other leading men of the day like Gary Cooper or Mickey Rooney, Bogart possessed the talent and the willingness to play villainous characters. He found great success playing immoral gangsters and criminals. Whether hero or villain, Bogart brought authenticity to his performances in his greatest film noirs.

This job isn't as simple as he first thought, struggling to keep the wannabe criminals in check and finding himself caught between two women. If that weren't enough a possibly cursed dog takes a liking to him.

Humphrey Bogart's sympathetic gangster, desperately searching for a normal life, manages to combine the actor's strengths as a hero with those of his villains for a powerful performance. This early film noir certainly has the tragic and dark that defines the genre, but it opens with plenty of humor making the tragic ending more impactful.

The film noir genre is often noted for its memorable and expressionistic cinematography. In Dark Passage, the early portion of the film was shot from the perspective of Bogart's character, who isn't seen till after the surgery. With its unique first-person perspective and byzantine plot, this film could make a list of great but underseen film noirs. The central relationship is emotionally captivating thanks to the natural chemistry of the leads, who are embodied brilliantly by real-life spouses Bogart and Lauren Bacall.

While private investigators are most often associated with the genre, dramas centered around boxing or boxers are also a hallmark of film noir with such notable films as Body and Soul and The Set-Up. This film, which was Humphrey Bogart's final film before dying from esophageal cancer, had a generally positive critical reception and received an Oscar nomination for best cinematography. It's easy to see why as The Harder They Fall expertly blends documentary-style realism with an outlandish plot involving blackmail and murder.

Frank McCloud (Bogart) is a WWII veteran visiting the family of a fallen comrade when he becomes trapped in their hotel. This is partially due to the hurricane sweeping the city, but mostly because of the armed gangsters who took shelter at the hotel. How much is he willing to sacrifice for his long-dead friend?

The final film where Bogart starred alongside his real wife Lauren Bacall, and the final film he would co-star with Edward G. Robinson who appeared in five films with Bogart. Bogart's traumatized veteran is a complex performance, but it was Claire Trevor who won the Oscar for best supporting actress for this film. With a plethora of memorable turns from some of Hollywood's best stars and character actors, Key Largo stands as one of Bogart's best gangster movies as well as one of his great film noirs.

To Have and Have Not (1944) - 7.8

Lauren Bacall looks down at Humphrey Bogart in To Have and Have Not.

The first of two gangster films where Bogart starred with James Cagney, who starred in some of the American Film Institute's best gangster movies. Cagney played the criminal with a heart of gold, which left Bogart to shine as the completely evil gangster trying to ruin his former partner. This film proved a financial success and an enduring classic of film noir. As the cruel antagonist, Bogart has fun with his one-dimensional role and shows why Warner Bros. cast him as the heavy in his 1930s films.

The Roaring Twenties (1939) - 7.9

Humphrey Bogart talks to James Cagney as he holds a bottle in The Roaring Twenties.

The lives of three men intersect at two very important moments in their lives while serving in The Great War and years later when they meet again and start a bootlegging business. Is the bond formed by soldiers in combat strong enough to stand the greed of gangsters and pressure of the law?

They bring very different styles to the similar characters they play, and them working off one another makes this film stand out.

The Big Sleep (1946) - 7.9

This film received positive attention from critics, and its reputation has only grown since then making an appearance in Time Magazine's "All-Time 100 Movies" list in 2005. The commentary on Hollywood morals is still relevant today and it is considered one of Humphrey Bogart's most iconic performances.
