On the day of the trip, the pair found themselves in a heavy stakes poker game Jack Dawson and Fabrizio De Rossi. Sven had bet their tickets as well as a pocket knife, some money and a pocket watch as a way of making their opponents go all in with everything they had, something Olaf was against. Despite Sven having two pairs, Jack beat him with a full house, resulting in them losing their tickets aboard the ship.
As Jack collected their winnings, Sven watched supportingly as Olaf grabbed the American and prepared to strike only to then strike Sven himself instead, knocking him out, due to the man having lost them tickets that cost them a fortune.
Jack whooped it up that he and Fabrizio were going to the United States. However, his revelry was sobered by the bartender of the tavern where the poker game occured, who bluntly stated "No, mate. Titanic is going to America, in five minutes!" motioning to a clock. Fabrizio and Jack quickly collected their winnings, stuffing as much money as they could in their pockets, then bolted out of the tavern onto the loading dock, where a seaman immediately boarded them as they presented their tickets. They were escorted to a third class cabin sharing it with two other Swedes, one of whom says to the other "Where is Sven?" in his own language.
This unfortunate event ironically saved Olaf's and Sven's lives, as both Jack and Fabrizio died when the ship sunk, which means he and Sven would most-likely have perished during the Titanic's sinking instead if he were to have won the game.
Behind the scenesEdit
After close examination of the boarding pass prop used in the film, it's shown that both Sven and Olaf's last name is Gundersen, indicating that they are related in some way.
He was portrayed by Dan Pettersson.
