Publicist Michelle Bega says Marshall died Tuesday in at a hospital in Burbank, California of complications from pneumonia after having a stroke.
Veteran filmmaker and TV personality Garry Marshall has died.
Marshall got his start pitching gags to comics like Joey Bishop and Phil Foster, before working his way into the writing rooms of shows like The Dick Van Dyke Show and The Lucy Show.
His most notable movie hit was 1989 romcom Pretty Woman, which starred Julia Roberts as an escort who becomes romantically involved with a workaholic businessman (played by Richard Gere) - with life-changing results.
Marshall's final three movies, Valentine's Day (2010), New Year's Eve (2011) and Mother's Day (2016) all featured all-star ensemble casts and interweaving storylines that centred around their titular holidays.
"Seinfeld" actor Jason Alexander, who appeared in "Pretty Woman", tweeted, "Garry Marshall gave me one of the best experiences I ever had in my career". Our condolences go out to his family at this very sad time.
The sitcom "Happy Days" and "Mork and Mindy" starring Robin Williams followed.
Everyone loved Garry Marshall.
Marshall defended his body of TV work, which won more viewers than honors, in his 1995 autobiography, "Wake Me When It's amusing", written with his daughter, Lori Marshall.
LOS ANGELES (AP) - Garry Marshall knew how to tug at moviegoers' heartstrings, whether with unlikely love in "Pretty Woman" or sentimental loss in "Beaches".
In 1974, the pair adapted Neil Simon's The Odd Couple for television, and then created perhaps their biggest hit, Happy Days. He portrayed the father of Oscar Madison (Matthew Perry) in an episode of "The Odd Couple" which aired on April 28. The film was such a hit the pair reunited for Runaway Bride in 1999.
The funeral services would be private and a memorial is being planned for his birthday on November 13.
Actor Henry Winkler, who forever earned the nickname the Fonz after starring in Marshall's "Happy Days", thanked the TV creator for giving him his "professional life".
Marshall's sister, actress and director Penny Marshall, starred as Laverne DeFazio in "Laverne & Shirley".
