Question: How long had the largest wrestling promotion in Mexico been in existence when Guerrera first appeared for them? Passage:The combination of Guerrera's in ring skills, natural charisma and unique mask quickly landed him a regular job working for Empresa Mexicana de Lucha Libre (EMLL), Mexico's largest wrestling promotion. On September 25, 1981 Fuerza Guerrera made his first appearance at a major EMLL show as he wrestled and defeated Negro Casas on EMLL's 48th Anniversary show. On November 6, 1983 Guerrera defeated Aguila Venezolana in a tournament final to win the vacant Mexican National Lightweight Championship, the first professional wrestling championships of his career. In May, 1984 Guerrera vacated the title when he moved from the lightweight weight class (between and ) and into the Welterweight weight class (between and ). On December 3, 1985 Fuerza Guerrera captured the Mexican National Welterweight Championship when he defeated Javier Cruz. Guerrera held the title for approximately 240 days before vacating the title as he left EMLL to work for other wrestling promotions in Mexico. By late 1988 Guerrera had returned to EMLL and captured the NWA World Welterweight Championship on October 4, 1988 when he defeated Solar II and won the highest ranking title in the Welterweight division at the time. Guerrera would go on to make several successful title defenses until he lost to Águila Solitaria on June 2, 1980. Guerrera regained the title three days later and went on to have an 808-day reign that included successful title defenses against Pantera II, Americo Rocca, his trainer Gallo Tapado, Misterioso and Octagón. In 1989 Guerrera also began working part-time in the Tijuana, Baja California based World Wrestling Association promotion, winning the WWA Welterweight Championship twice in 1989 and 1990.

Question: What films did Ron Perlman work on the year Sklenar was cast in the film Indigo Valley? Passage:He was then cast as Edward Mapplethorpe in the 2018 biographical drama film Mapplethorpe, which follows the life of New York photographer Robert Mapplethorpe. It screened at Tribeca Film Festival in 2018 where it was named a Runner-up in the U.S. Narrative Competition section. Sklenar received positive critical acclaim from multiple media outlets for his performance in Mapplethorpe, including from Boy Culture who praised him for "[having] maximum impact in [his] psychologically charged scenes with [Matt] Smith" and Screen Daily who said:"As the brother and photographer Edward Mapplethorpe, who Robert [Mapplethorpe] forced to change his name, Brandon Sklenar is a fragile mix of awe and fear." He appeared in the 2018 biographical drama film Vice, opposite Amy Adams, Steve Carell, Christian Bale and Sam Rockwell. The film explores the life of politician Dick Cheney and is directed by Academy Award-winner Adam McKay. Sklenar will appear in Amir Naderi's upcoming film Magic Lantern, in addition to films The Last Room and Glass Jaw. In June 2018, Sklenar was also cast in the independent drama film Indigo Valley, which is based on director Jaclyn's Bethany's short film of the same name. That same year, Sklenar was cast in a lead role in London Calling, a noir crime thriller that weaves the British gangster genre with the American western, opposite Ron Perlman, Malcolm McDowell, Nicholas Braun and Leven Rambin.

Question: Where did the team that the Sooners faced in the final game of 2009 season play their home games? Passage:However, before the season began, Gresham suffered a season-ending injury. During the season opener against BYU, Bradford suffered an injury to his shoulder that forced him to sit out the next several games. The Sooners would go on to lose that game and their fourth game against Miami. Bradford returned for game number five against Baylor, but reinjured his shoulder the next week against Texas, ending his season and giving the Sooners their third loss of the season. The Sooners would continue to suffer many injuries throughout the remainder of the season including losing offensive linemen Jarvis Jones and Brody Eldridge, and defensive players Tom Wort, DeMarcus Granger and Auston English for the season. With freshman Landry Jones now leading the offense, the Sooners would go on win every home game from that point forward, including a season-ending win over in-state rival Oklahoma State, extending their NCAA-leading home winning streak to 30 games. However, the Sooners would also lose all but one of their away games. Oklahoma ended the regular season with seven wins and five losses (5–3 in the Big 12). The game marked Oklahoma's third appearance in the Sun Bowl. They were a perfect 2-0 in their previous games. In 1981, they defeated Houston 40–14, and in 1993, they defeated Texas Tech 41–10.
