Steward Turnbull is a character in the Titanic 2012 miniseries.
During the sinking, he guards the Third-Class gate, preventing anyone from leaving. When Jim Maloney steps in, Turnbull heavily shoves Jim away, and orders everyone to stand back. However, he is attacked, and some passengers escape.
When fireman Mario Sandrini appears on the other side of the closed gate and causes an uproar among the trapped passengers, Turnbull opens the gate and drags him in. All Third Class passengers escape, and Turnbull desperately tries to close it again, but he is pushed to the side and gives up. Meanwhile Sandrini is locked up with the Italians.
Turnbull leaves steerage and tries to get to the deck. Steward Sandrini stops him to ask where the Italians are locked up. Eventually, he reveals where they are. When Sandrini goes to rescue them, Turnbull angrily shouts at him, "You won't get them out! The door is locked! And it'll stay locked, until it hits the ocean bed!!!"
Unlike many of the other passengers Turnbull and his crew did not make for the safety of the lifeboats at the expense of women, children and the poorer passengers. In fact they headed down further into Titanic, only to find it their last moments. Turnbull died during the sinking.
Personality
He is a mean, strict and hot-tempered steward on board Titanic. In Episode 3, he guards the Third-Class gate and stands there as the poor passengers clamor in panic. When Jim Maloney gets to him, Turnbull shoves him.
He is somewhat arrogant and rebellious: doesn't like following the rules and doesn't care about anyone but himself -- He is conceited and sociopathic. Turnbull is a rude, impatient, destructive, vain, egomaniacal, manipulative, and somewhat narcissistic steward who will go to any length to get what he wants, even if it involves bribing or attempting to let the Third-Class passengers drown in steerage. He is very conservative, narrow-minded, and misogynistic to the extent that he disapproves of women reading because he regards ideas as dangerous to them, and believes that women's only purpose in life is to serve men.
