Wright starred as Princess Buttercup in the movie, which would serve as her breakout film role after starring as Kelly Capwell on the soap opera Santa Barbara.
In September, the actress reunited with several of her Princess Bride castmates (including Elwes, 58, Mandy Patinkin, Billy Crystal, Carol Kane, Chris Sarandon, Wallace Shawn and Christopher Guest) for a virtual table read of the iconic film.

As for Dylan's role in Flag Day, which is based on a true story and made its debut at Cannes this year, she plays Jennifer Vogel, the daughter of Sean's John Vogel, a man who raised her in a fantastical world but has a con-artist past that Jennifer is forced to come to grips with as an adult.
And Wright — who was married to Sean from 1996 to 2010 and with whom she also shares son Hopper Penn — is a big reason Dylan agreed to star in Flag Day, which also features an appearance from brother Hopper, 27.
"She very simply said, 'I've never worked with a better director than your dad. It was the most amazing experience I've ever had as an actor,' " Dylan said of Wright, whom Sean directed in 2001's The Pledge. "So I trusted that."
Flag Day hits theaters Aug. 20.
