The iconic flick "Annie Hall," which solidified Diane Keaton as a household name back in 1977, is celebrating its 40th anniversary on April 20, 2017! In honor of the legendary film reaching this milestone, we're taking a look back at its star's life in photographs! Keep reading to see the actress's trajectory…

Diane Keaton, born Diane Hall, was raised in Southern California, where she caught the acting bug at a young age. After graduating from high school in Santa Ana, California, she moved to New York City to pursue her dreams and studied at the Neighborhood Playhouse School of the Theater. The move paid off, as she found work on Broadway and earned a role starring opposite Woody Allen in his production of "Play It Again, Sam," which netted her a Tony nomination.

While working together on Broadway, Diane Keaton and Woody Allen struck up a romantic relationship. The duo grabbed dinner one night after a late rehearsal on "Play It Again, Sam" and things took a more serious turn, resulting in them living together during the play's production. The romance was short-lived, but neither star ever opened up about the details. By the early '70s, they'd split, though they remained great friends and continued to work together throughout their careers.

From the stage to the silver screen! Diane Keaton landed her first film role in 1970's "Love and Other Strangers," which wasn't a huge movie but got her recognized by a very big Hollywood name — Francis Ford Coppola. The director selected Diane for the role of Kay Adams, infamous mobster Michael Corleone's better half, in the 1972 film "The Godfather." That flick catapulted Diane's career to another level, as it was both the highest grossing film of the year and an Academy Award Best Picture winner.

After appearing in "The Godfather" and sequel "The Godfather II," Diane Keaton shifted gears to collaborate with Broadway partner and former boyfriend Woody Allen. The pair brought "Play It Again, Sam" — the play that earned her a Tony nomination — to the big screen in 1972.

One of Diane Keaton's most iconic roles came in 1977 when she once again teamed up with Woody Allen for "Annie Hall." The film portrayed Diane as the quirky, eccentrically dressed Annie, and many considered it to be loosely based on Diane and Woody's relationship in the early '70s. The name even originated from Diane's nickname (Annie) and her real surname (Hall).

After "Annie Hall," Time magazine hailed Diane Keaton as "the funniest woman now working in films." But later that year, she surprised fans by taking on a dramatic role in 1977's "Looking For Mr. Goodbar." The film, based on a novel, starred Diane as a woman living a double life — a teacher at a Catholic school for the deaf by day and a promiscuous woman by night.

"Annie Hall" landed Diane Keaton her first Academy Award nomination for Best Actress — and she won! The star attended the Oscars in true Annie form — wearing a pantsuit — on April 3, 1978.

Another Hollywood romance! Diane Keaton started dating then-tabloid fixture Warren Beatty in 1978 after the two met on the set of "Reds." Unfortunately, the relationship was short-lived, as Diane found it difficult to date someone with Warren's level of fame. The two split after "Reds" filming wrapped, but just like her relationship with Woody, afterward, the two remained pals. Though she didn't finish the film with a beau, she would go on to earn another Academy Award nomination.

Diane Keaton and Woody Allen reunited for 1979's "Manhattan," which would be their last film together in the '70s. The romantic comedy was filmed in black and white and also starred Meryl Streep and Mariel Hemingway. This flick is often considered one of Woody's funniest films. It marked the sixth time Diane and Woody had worked together on the big screen.

They can't all be major hits! In 1984, Diane Keaton had her first big box office flop with 1984's "The Little Drummer Girl." Her first foray into the action genre was met with terrible reviews and made little money. Unfortunately for Diane, this wouldn't be her first big bomb. The late '80s saw her starring in universally panned films including Walt Disney's "The Good Mother" in 1988.

In the late '80s, Diane Keaton delved into another professional endeavor — directing! It started with her first effort in 1987 on a film called "Heaven," then progressed into directing made-for-TV movies and music videos later in the decade.

After a string of box office disappointments, Diane Keaton delivered a big hit in 1991. On the heels of critical failure "The Lemon Sisters" in 1990, she played the matriarch of the family in "Father of the Bride."

Diane Keaton once again returned to the mobster world in 1990's "The Godfather: Part III," reprising the role of Kay. But this time, life imitated art. As Diane played Al Pacino's on-screen ex-wife, the romance bled into real life and the actors started dating after filming ended.

Another year, another sequel! In 1995, Diane Keaton reprised her role as Nina Banks alongside Kimberly Williams, Steve Martin and Martin Short in the eagerly anticipated sequel "Father of the Bride Part II." In this installment, Nina finds herself pregnant at the same time as daughter Annie. The film received mixed reviews and wasn't able to duplicate the magic of the first film.

Diane Keaton made a major life decision at age 50 when she adopted her first child, daughter Dexter Dean, in 1996. She was seen with a friend pushing the tot in a stroller later that year. She would later adopt one more child, a son named Duke, in 2001.

The '90s were good to Diane Keaton, who starred in her biggest box office success of the decade, "The First Wives Club," in 1996. She played Annie MacDuggan-Paradis alongside Bette Midler and Goldie Hawn. The film received mixed reviews but was a big financial hit. Most credit it to the support from middle-aged women who were excited to see themselves represented on-screen. "The First Wives Club" was the 11th-highest-grossing flick of 1996.

Diane Keaton returned to the Academy Awards in 1997 with a nomination for her work in "Marvin's Room." The drama starred Diane as Bessie, a woman suffering from leukemia, and co-starred Meryl Streep and a young Leonardo DiCaprio. She didn't take home the top prize, but she did attend the event with "Father of the Bride" co-star Steve Martin! The two attended the ceremony together in 1995 as well.

In the early '00s, Diane Keaton had a few poorly received films at the box office and dabbled in some low-budget flicks before striking gold with the 2003 film "Something's Gotta Give." She starred alongside Jack Nicholson in the romantic comedy about two older people in love. Her portrayal of Erica Barry garnered her a Golden Globe and also netted her one more Academy Award nomination.

One place you'll never catch Diane Keaton? A plastic surgeon's office. The actress was vocal about her distaste for the commonplace practice in Hollywood, opening up to More magazine in 2004. "I'm stuck in this idea that I need to be authentic … My face needs to look the way I feel," she told the outlet.

Despite always having a minimalist approach to her own personal beauty routine, Diane Keaton's staunch opinions against plastic surgery did not go unnoticed. In 2006, a major beauty line recruited the star for its advertising campaigns: She became a L'Oreal spokesperson at 60!

2007 saw Diane Keaton playing Mandy Moore's meddling mom in "Because I Said So." Though it didn't bomb at the box office, it received an overwhelming amount of awful reviews — but ended up providing Diane with a first in her career: The actress received her first Golden Raspberry Award at the Razzies, which celebrate the worst in film every year.

A published author! Diane Keaton wrote a memoir, which was published in 2011, called "Then Again." Much of the content came from an unexpected source — her mother's old journals!

Diane Keaton posed with her children, Dexter Keaton and Duke Keaton, at the premiere of her 2014 flick "And So It Goes" in East Hampton, New York, on July 6, 2014. The film was panned by critics, but she had a cute mommy moment on the red carpet with her darling kids.

Diane Keaton continues to work in her 70s, most recently lending her voice to 2016's "Finding Dory" and starring on HBO's "The Young Pope." Next up for the star? "Homestead" alongside James Norton, which is set to debut in 2017.
