Doctor Stephen Maturin (Paul Bettany) and Captain Jack Aubrey (Russel Crowe) aboard the HMS Surprise in Master and Commander: The Far Side of the World (2003).
This is one of my Top Ten favorite films of all time, in no small part because I am a huge fan of the series of 20 novels upon which it is based.
Some of you whippersnappers out there probably recognize these two actors for their work in the MCU: Bettany played The Vision, and Crowe played Zeus.
