The movie musical The Sound of Music and Princess Cruises both commemorate their 50th birthday this year. As part of the celebration, Princess Cruises is making the seas come alive with the sound of music.

The cruise line is screening the movie on all 18 of its cruise ships, as well as featuring sing-alongs, trivia games and other movie-themed experiences throughout the year.

“The Sound of Music isn’t just a classic film – watching the movie together is a classic family activity,” said Jan Swartz, Princess Cruises president. “In a year in which both Princess Cruises and The Sound of Music mark their golden anniversaries, this is truly a fun and memorable way to join in the celebrations.”

Princess Cruises also is offering movie fans chances to win a free cruise and a $500 onboard gift card every month through December 2015.

The Sound of Music will be shown once on every sailing throughout 2015 on Princess Cruises giant Movies Under the Stars top deck screens, with the sing-a-long version featured in the Princess Theater. Songbirds can meet and rehearse for a special The Sound of Music edition of Princess Pop Choir and a themed Trivia Challenge will test fans’ movie knowledge. 

A phenomenon upon its debut in 1965, The Sound of Music won five Academy Awards, including “Best Picture” and continues to inspire audiences around the world with unforgettable songs including “Do-Re-Mi,” “My Favorite Things,” “Climb Every Mountain,” and “The Sound of Music.”

Starring Oscar winners Julie Andrews and Christopher Plummer, the film follows Maria (Andrews), the warm-hearted young woman who brings joy and music to Captain von Trapp (Plummer) and his seven children.
