Hollywood icon Garry Marshall, who entertained audiences with countless box office hits and successful TV shows like Happy Days, Pretty Woman, and The Princess Diaries, passed away Tuesday at the age of 81, his rep confirmed. The famed director passed away in a Burbank, Calif., hospital after suffering complications from pneumonia following a stroke.

Marshall started out script writing for TV sitcoms before focusing his talents on the big screen, and his success as a writer and director helped launch the careers of many a Hollywood superstar. One such actor: Julia Roberts, who described in InStyle's June issue how the director jumpstarted her career with her iconic role in Pretty Woman.

"He was really a great shepherd for me in the beginning," the 48-year-old star said. "You can never give credit for anything to one person. Singular credit just doesn't exist. But if I were to single someone out as a person whom I feel very indebted to, in what I realized the other day is my 30-year career, it would be Garry."

"He knows how to touch all those places in our hearts that we just sit around longing for people to tap into," she said. "He's a master of that. I love working for him. And we have somehow managed to work together, almost scientifically, every 10 years."

Stars such as Goldie Hawn, Ron Howard, Lea Michele, and Rob Lowe honored the talented man whose career spanned more than half a century by posting tributes on social media. See them below.
