Rough Crossing is a 1984 comedic play by British playwright Tom Stoppard, "freely adapted from Ferenc Molnár's Play at the Castle". Set on board the SS Italian Castle, it follows world-renowned playwrights Sandor Turai and Alex Gal in their attempts to preserve, with the assistance of the unorthodox cabin steward Dvornichek, the relationship of their composer, Adam Adam, and his love, the leading lady Natasha Navratilova, despite the interference of lothario actor Ivor Fish.
