Input: The story of the rise of politician Willie Stark from a rural county seat to the governor's mansion is depicted in the film. He goes into politics, railing against the corruptly run county government, but loses his race for county treasurer, in the face of unfair obstacles placed by the local machine. Stark teaches himself law, and as a lawyer, continues to fight the local establishment, championing the local people and gaining popularity. He eventually rises to become a candidate for governor, narrowly losing his first race, then winning on his second attempt. Along the way he loses his innocence and becomes as corrupt as the politicians he once fought against. When his son becomes paralyzed following a drunk driving accident that kills a female passenger, Stark's world starts to unravel and he discovers that not everyone can be bought off. The story has a complex series of relationships. All is seen through the eyes of the journalist, Jack Burden, who admires Stark and even when disillusioned still sticks by him. Stark's campaign assistant, Sadie is clearly in love with Stark and wants him to leave his wife, Lucy. Meanwhile, Stark philanders and gets involved with many women, taking Jack's own girlfriend, Anne Stanton, as his mistress. When Stark's reputation is brought into disrepute by Judge Stanton (Anne's uncle), he seeks to blacken the judge's name. When Jack finds evidence of the judge's possible wrongdoing, a quarter century earlier, he hides it from Stark. Anne gives the evidence to Stark, who uses it against her uncle, who immediately commits suicide. Anne seems to forgive Stark, but her brother, the surgeon who helped save Stark's son's life after the car crash, cannot. The doctor eventually assassinates Stark after Stark wins an impeachment investigation. The doctor in turn is shot down by Sugar Boy, Stark's fawning assistant. The main plot is a thinly disguised version of the rise of real-life 1930s Louisiana Governor, Huey Long, Long's efforts to blacken the name of Judge Benjamin Pavy, and Long's assassination by the Judge's son-in-law (compared to nephew, as in the film), Dr. Carl Weiss.

Now complete the following example -
Input: At a jousting tournament in 14th-century Europe, young squires William Thatcher, Roland, and Wat discover that their master, Sir Ector, has died. If he had completed one final pass he would have won the tournament. Destitute, William wears Ector's armour to impersonate him, winning the tournament and taking the prize. Although only nobles are allowed in tournaments, William is now inspired to compete and win more prizes. Roland and Wat would rather take their winnings and leave, but William convinces them to stay and train him to joust. Along the way to his first tournament in Rouen, the trio encounters a young Geoffrey Chaucer, who is also destitute and agrees to forge the patent of nobility that will allow William to enter under the assumed name of "Sir Ulrich von Liechtenstein" from Gelderland. At the tournament, William is brought before Simon the Summoner and Peter the Pardoner: Chaucer has a gambling problem and is in their debt. William demands Chaucer be released and promises payment. In the course of competition, William's armor is damaged very badly. He goads Kate, a blacksmith, to repair it without payment and goes on to win the tournament's sword event. In the joust, he faces Sir Thomas Colville, who withdraws from the tournament after being injured by William, though they exchange a ceremonial pass so that Colville can retain the honor of never having failed to complete a match. The proceedings are observed by Jocelyn, a noblewoman with whom William has become infatuated, and Count Adhemar, a rival both in the joust and for Jocelyn's heart. In the final joust, Adhemar defeats William. At the prize ceremony, William vows revenge on Adhemar who then taunts William by telling him that he has been weighed, measured and found wanting. William then uses some of his winnings from the sword event to pay off Chaucer's debt. 
Question: Who faces Sir Thomas Colville in a joust?
Output: 


Output: William
