Why Humphrey Bogart and Lauren Bacall Were Hollywood's Ultimate '40s Power Couple

If you're a lover of Golden Age Hollywood, chances are good that you've swooned over Humphrey Bogart and Lauren Bacall. The two actors, who married in 1945, starred in four classic films together — To Have and Have Not (1944), The Big Sleep (1946), Dark Passage (1947) and Key Largo (1948) — and were known for their unparalleled chemistry.

Sadly, Bogart and Bacall's marriage came to a premature end in 1957, when Bogart died at 57. The iconic charisma they brought to their beloved cinematic collaborations truly never gets old. Here are some fascinating facts you may not have known about the captivating couple.

Bogart and Bacall's relationship had a scandalous start

Humphrey Bogart and Lauren Bacall met during the filming of To Have and Have Not. At the time, Bacall was just 19, while Bogart was 45 and still married to his third wife, actress Mayo Methot.

Bogart and Bacall started a steamy affair, and the couple married in 1945. In 1949 they had a son, Stephen Humphrey Bogart. He went on to author three books about his famous family. Their daughter, Leslie Howard Bogart, was born in 1952.

Watching To Have and Have Not, it's easy to see the origins of Bogey and Bacall's real-life romance, as the rugged leading man and the glamorous femme fatale are impossible to look away from.

It's also hard to believe that To Have and Have Not was Bacall's very first film. Right from the start, she had a perfectly self-assured screen presence, and projected a confidence and maturity well beyond her years.

Surprisingly, Bacall admitted to having stage fright, telling Vanity Fair that she had to "hold my trembling head still... keep it down, chin low, almost to the chest, and eyes up at Bogart.” This move led her to develop her signature sultry gaze.

Their marriage wasn't always easy

Bacall was becoming deservedly famous in her own right just as she and Bogart got married. With two A-listers, one a veteran and one a rising star, their marriage was the subject of much fanfare in the media.

While Bacall said, "I fairly often have thought how lucky I was. I knew everybody because I was married to Bogie, and that 25-year difference was the most fantastic thing for me to have in my life," and the pair had an undeniably loving and beautiful relationship, they also ran into some challenges.

Bacall admitted that being with Bogart led her to miss out on a number of potential roles in the '40s and '50s, saying, "he wanted a wife. He didn’t want an actress." She was rightly frustrated by people seeing her as Bogie's wife first and an actress second, but at the end of the day, she said, "I was happy being his wife. I loved it. Because I really loved him."

Bogart was also known for his hard-living ways, and was a big drinker. In fact, it was Bacall who coined the term "Rat Pack," when she walked in on Bogart, Frank Sinatra and their other celebrity pals during a night of drunken debauchery and said, "You look like a goddamn rat pack."

Humphrey Bogart and Lauren Bacall were only in four movies together

Bogart and Bacall loom so large in the mythology of classic Hollywood that it's easy to forget they were only in four movies together.

Two of those movies, the romantic drama To Have and Have Not and the film noir The Big Sleep, were directed by Howard Hawks, who discovered Bacall and helped shape her into the icon we know today after his wife spotted her on a 1943 Harper's Bazaar cover when she was still an unknown model.

Bogart and Bacall's third movie together, Dark Passage, was a gritty thriller, and their final film was the 1948 crime drama Key Largo.

Each of their movies has a distinctly different feel, but their chemistry unites them — and makes them eminently watchable nearly 80 years later.
