Earlier this week, we reported that the legendary star Christopher Plummer had died at the age of 91 after falling at his home in Connecticut. Now, three of the actors who played his children in the 1965 classic movie The Sound Of Music are speaking out to pay tribute to him.

Angela Cartwright, Nicholas Hammond and Kym Karath played Brigitta, and Friedrich Gretl von Trapp in the movie.

“Christopher Plummer showed this 14-year-old aspiring actor what acting really was,” Hammond said to Fox News. “Uncompromising in his search for the truth in any role, from Hamlet to Lear to Tolstoy. His re-invention of the role of Captain von Trapp gave the film a gravitas and integrity the stage musical had never had.”

“He made every film and every play he did better by his presence and craft,” he added. “I idolized him as my film father, he was my role model for the years that followed. It is a huge blow to those of us in the ‘Sound of Music’ family, we, along with the whole world, will miss him very much.”

Cartwright also had words of praise to honor Plummer.

“I was very sad to hear about Christopher Plummer’s passing,” Cartwright said. “‘The Sound of Music’ cast has always felt like family, so losing Christopher is difficult. He was so very talented and brought such originality and edge to the roles he played. He had a long 91 years… but his legacy will live on forever.  So long, farewell Captain.”

“I am deeply saddened by the loss of Chris Plummer,” added Karath. “He was a lovely, brilliantly talented, and incredibly witty man. He was the best of film fathers and a friend. He will be missed by so many.”

This comes after Julie Andrews, who also starred in The Sound Of Music, released a statement honoring Plummer as well.

“The world has lost a consummate actor today and I have lost a cherished friend,” Andrews told Entertainment. Tonight. “I treasure the memories of our work together and all the humor and fun we shared through the years. My heart and condolences go out to his lovely wife Elaine, and his daughter Amanda.”
