Olson was signed to a film contract by Paramount Pictures in 1948, and, after a few supporting roles, producers began to consider her for more prominent parts. She was up for the role of Delilah in Cecil B. DeMille's film Samson and Delilah (1949), for which Olson later said she was not suited. She was passed over in favor of Hedy Lamarr.

Her first big role came in Canadian Pacific (also 1949) with Randolph Scott, then Billy Wilder cast her for his upcoming project. In Sunset Boulevard (1950), she played Betty Schaefer, for which she gained an Academy Award nomination for Best Supporting Actress. Her pairing with William Holden was considered a success, and she appeared with him in three other films (Union Station, Force of Arms, and Submarine Command, the second and third released the following year), but none repeated their success in Sunset Boulevard.

Olson's success in "Sunset Boulevard" also led to her being cast in the 09/15/1950 episode of the radio program Dimension X, titled "Hello Tomorrow".

Other film credits include Big Jim McLain (1952), So Big (1953), Battle Cry (1955), and Dumbbells (2014).

Olson made several appearances in films for the Walt Disney studio. The Absent-Minded Professor (1961) and Son of Flubber (1963) paired her with Fred MacMurray and were popular with movie-goers. She also appeared alongside Hayley Mills in Pollyanna (1960) and Dean Jones in Snowball Express (1972). Olson then moved to New York City where she appeared on Broadway.

Throughout the 1960s and 1970s, she did guest roles on television. Olson guest-starred on the Television series The Big Valley playing the mother of Ron Howard in the December 1, 1965, episode titled Night of the Wolf. Olson is the only female guest starring on The Big Valley to ever marry the character Nick Barkley.

Olson has been retired since the mid-1980s, although she made a brief, uncredited appearance in Flubber, the 1997 remake of The Absent-Minded Professor.

In 1950, Olson became the third wife of lyricist Alan Jay Lerner. They had two daughters, Liza and Jennifer.^[3] They divorced in 1957.

In 1962, she married long-time Capitol Records executive Alan W. Livingston, best known for creating Bozo the Clown and for signing Frank Sinatra, Judy Garland and other singers to Capitol. He died in 2009; they had one son, Christopher.^[3]

Olson is a registered Democrat and has donated to the party under her married name.^[4]
