Background: Tropic Thunder is a 2008 black satirical action comedy film directed by Ben Stiller, who stars with Jack Black and Robert Downey Jr. as a group of prima donna actors who are making a fictional Vietnam War film. When their frustrated director drops them in the middle of a jungle, they are forced to rely on their acting skills to survive the real action and danger. The screenplay by Justin Theroux, Stiller, and Etan Cohen was from a story by Stiller and Theroux. The film was produced by Stuart Cornfeld, Stiller and Eric McLeod for Red Hour Productions and DreamWorks Pictures as an international co-production between the United States, Germany, and the United Kingdom.
Context: Although Southern California and Mexico were considered for the main unit filming, the Hawaiian island of Kaua'i (where Stiller has a home) was selected for the majority of the shooting. Kaua'i was chosen over Mexico because a tax credit for in-state spending was negotiated with the Kaua'i Film Commission. John Toll, the cinematographer, stated the island was also selected for its similarity to Vietnam, based on its dense foliage, variety of terrains, and weather. Kaua'i was first scouted as a possible location to film Tropic Thunder in 2004. Stiller spent more than 25 hours over 6 weeks exploring the island, using all-terrain vehicles, boats, and helicopters. After the film was greenlit by DreamWorks in 2006, pre-production lasted for six months, most of this time spent on scouting additional locations for filming. Filming for the Los Angeles and interior scenes occurred on sets at Universal Studios in Hollywood.  Tropic Thunder was the first major studio production on Kaua'i in five years. After filming was completed, it was deemed the largest production filmed on the island to date, and contributed more than $60 million to the local economy. Tim Ryan, the executive editor of Hawaii Film & Video Magazine, commented on the filming on the island: "I think Tropic Thunder will give Kaua'i much needed and long idled publicity in the production arena ... It should put Kaua'i back on the production consideration radar." Preliminary production crews were on the island starting in December 2006 and principal photography began in July 2007, with filming lasting thirteen weeks over seven separate locations on the island. Much of the filming took place on private land as well as conservation status designated areas. Casting calls on the island sought 500 residents to portray the villagers in the film. Two units shot simultaneously on the island from the ground, and an aerial unit shot from helicopters. Many of the sets and the bridge used for one of the final scenes were built in three months. The island's erratic weather hampered filming with rain and lighting issues. The crew also faced complications in moving the equipment and cast due to the difficult terrain.  The film advising company Warriors Inc. was enlisted to ensure the war scenes, including the attire worn by the actors, looked authentic. Former members of the U.S. military taught the actors how to handle, fire, and reload their weapons, as well as perform various tactical movements. The opening war scene was filmed over three weeks and required fifty stuntmen. Animatics were used to map out the necessary camera angles for filming.

Problem: Background: De Benneville "Bert" Bell (February 25, 1895 - October 11, 1959) was the National Football League (NFL) commissioner from 1945 until his death in 1959. As commissioner, he introduced competitive parity into the NFL to improve the league's commercial viability and promote its popularity, and he helped make the NFL the most financially sound sports enterprise and preeminent sports attraction in the United States (US). He was posthumously inducted into the charter class of the Pro Football Hall of Fame. Bell played football at the University of Pennsylvania, where as quarterback, he led his team to an appearance in the 1917 Rose Bowl.
Context: Bell entered Penn in the fall of 1914 as an English major and joined Phi Kappa Sigma. In a rare occurrence for a sophomore, he became the starting quarterback for Penn's coach George H. Brooke. On the team, he also was as a defender, punter, and punt returner. After the team's 3-0 start, Bell temporarily shared possession of his quarterbacking duties until he subsequently reclaimed them later in the season, as Penn finished with a record of 3-5-2.  Prior to Penn's 1916 season, his mother died while he was en route to her bedside. Nevertheless, he started the first game for the Quakers under new coach Bob Folwell, but mixed results left him platooned for the rest of the season. Penn finished with a record of 7-2-1. However, the Quakers secured an invitation to the 1917 Rose Bowl against the Oregon Ducks. Although the best offensive gain for Penn during their 20-14 loss to Oregon was a 20-yard run by Bell, he was replaced late in the game at quarterback after throwing an interception.  In the 1917 season, Bell led Penn to a 9-2 record. Afterwards, he registered with a Mobile Hospital Unit of the US Army for World War I and was deployed to France in May 1918. As a result of his unit participating in hazardous duty, it received a congratulatory letter for bravery from General John J. Pershing, and Bell was promoted to first sergeant. After the war, Bell returned to the United States in March 1919. He returned to Penn as captain of the team in the fall and again performed erratically. The Quakers finished 1919 with a 6-2-1 record. Academically, his aversion to attending classes forced him to withdraw from Penn without a degree in early 1920. His collegiate days ended with his having been a borderline All-American, but this period of his life had proven that he "possessed the qualities of a leader."
Question: what did he do there?
Answer:
In a rare occurrence for a sophomore, he became the starting quarterback for Penn's coach George H. Brooke.
