Day was among the most popular screen actresses in history, starring in dramas, musicals and innocent sex comedies alongside leading men such as Frank Sinatra, Rock Hudson, Jimmy Stewart, James Cagney and Clark Gable.
Though Day’s last film role was in the 1968 comedy "With Six You Get Eggroll,” the singer-actress has remained an icon of old Hollywood. She continues to be remembered for her versatile performances, one of which (1959's “Pillow Talk") earned her an Oscar nomination.
“Star Trek” actor George Takei remembered Day as being “synonymous with Hollywood icon.”
Takei's "Star Trek" co-star William Shatner also offered his condolences to the "World's Sweetheart."
Journalist Katie Couric posted a video montage of Day's acting, calling her "one of a kind."
Actor Antonio Banderas thanked Day for sharing her talent.
The Tribeca Film festival Twitter account paid tribute to Day, a legendary star it says “warmed our hearts” for years.
Stella McCartney, an English fashion designer and daughter of Beatles musician Paul McCartney, wrote that Day was an "iconic woman" she was honored to have met.
Actor and comedian Seth MacFarlane posted a video of Day singing "Shaking the Blues Away" from the 1955 film "Love Me or Leave Me," which she starred alongside leading man James Cagney, to show his appreciation for her talent.
