Timeless classic film The Sound of Music will play once on every Princess Cruises sailing from mid Apr for the rest of the year as part of a new partnership between the line and Twentieth Century Fox Home Entertainment.
The pact comes due to both the movie and the line celebrating 50th anniversaries in 2015.
In addition to movie screenings, Princess will host sing-along sessions, trivia games and other movie themed experiences.
Activities will also allow guests to join a Princess Pop Choir.
