Given the following context:

Captain Crowther has five of his crew replaced at short notice before a new cruise voyage begins. Not only does he get the five most incompetent crew men ever to sail the seven seas, but the passengers turn out to be a rather strange bunch too.
The SS Happy Wanderer is the cruise ship and after this voyage, Crowther hopes to get a job as captain on a transatlantic ship, promising the crew members their jobs will be safe under the new captain.  Starting off from England, the Happy Wanderer calls at unnamed ports in Spain, Italy and North Africa before going home again.
Single ladies Gladys and Flo take the cruise, with Flo hoping to find a husband. Bridget is her usual dotty and entertaining self, and one unnamed passenger never disembarks but always goes straight to the bar to drink, to forget an unidentified woman. The crew and passengers settle in as the ship leaves port and head chef Wilfred Haines finds out he is seasick. Mario Fabrizi makes a quick appearance as one of the cooks under Haines. Ed Devereaux, best known for the part of Matt Hammond in the Australian TV series 'Skippy', appears as a Young Officer.
Gladys and Flo fall for the PT instructor Mr Jenkins but nothing comes of it, especially when Flo turns out to be hopeless in the gym. Meanwhile, the new men try to impress Crowther but disaster follows disaster with him getting knocked out and covered in food at a party.

answer the following question:

What is the first name of the man who works under Wilfred? 

Mario
