The 41-year-old actress shared an old photo in Hoffman's honor from their time spent together filming the 1999 thriller The Talented Mr. Ripley. "Ischia 1998, post dinner, post shooting . . . Philip was a true genius. #philipseymourhoffman," Paltrow wrote as the caption. In the old snapshot taken on an island in the Tyrrhenian Sea in Italy, Paltrow poses next to a smiling Hoffman while giving a big laugh to the camera. Fellow costar Jude Law -- looking much younger -- is also in the photo posing for the group shot alongside another woman.
Hoffman tragically passed away at the age of 46 on Sunday. The actor was found dead, from an apparent drug overdose, in his Greenwich Village apartment by a friend, playwright David Bar Katz. The NYPD confirmed that Katz found Hoffman alone in the bathroom with a needle in his arm.
"I saw him last week, and he was clean and sober, his old self," Katz told the New York Times. "I really thought this chapter was over." The Master actor completed a 10-day rehab stint in May 2013 after a relapse following 23 years of sobriety.
Hoffman is survived by three young children and longtime partner, Mimi O'Donnell. A source told Us Weekly that friends and family began to worry on Sunday when he failed to pick up his children -- son Cooper and daughters Tallulah and Willa -- from costume designer O'Donnell. An insider told Us that Hoffman had planned to watch the Super Bowl with his son.
