Titanic - Easter Eggs & Hidden Details

During the initial boarding scene in Southampton, James Cameron makes a brief appearance as a bearded man in the third-class line getting checked for lice. He also has a voice cameo, saying 'Full speed ahead!' a bit later.

In the final dream/afterlife scene, when Rose meets Jack on the Grand Staircase, the clock behind them reads 2:20. This is the exact time the RMS Titanic officially sank on April 15, 1912, symbolizing that their reunion is taking place in a moment frozen outside of mortal time, at the very minute their physical separation occurred.

Edward Kamuda, the then-president of the Titanic Historical Society, has a non-speaking cameo as an extra walking on the deck as the ship leaves the dock. This was a nod to the extensive historical consultation that went into the film's production.

James Cameron was heavily influenced by the 1958 British film about the disaster, 'A Night to Remember'. He included several homages, including a scene where a character tells the ship's designer, Thomas Andrews, 'But this ship can't sink!', and the poignant depiction of the ship's band playing on deck as the vessel goes down.
