Question: What was the previous episode that the 2005 one where the tenth doctor was introduced followed? Passage:The regeneration of the Ninth Doctor into the Tenth at the end of "The Parting of the Ways" (2005) used computer effects to morph Christopher Eccleston into David Tennant. In the episode of Doctor Who Confidential accompanying the episode "Utopia" (2007), where the same effect is used for the Master's regeneration, it is stated that the production team decided that this would be a common effect for all future Time Lord regenerations, rather than each regeneration being designed uniquely at the whim of the individual director. This style of transition is seen again in "The Stolen Earth"/"Journey's End" (2008) both when the Doctor undergoes an aborted regeneration, and when his hand spawns a clone in the second part; in The End of Time (2010) during which Matt Smith took over the role as the Eleventh Doctor; in "The Impossible Astronaut" when the Doctor is shot twice and seemingly killed; in "Day of the Moon" when a young girl regenerates; and in "Let's Kill Hitler" when Mels (Nina Toussaint-White) is shot and regenerates into River Song (Alex Kingston). "The Night of the Doctor" and "The Day of the Doctor" subsequently use the effect to show the Eighth Doctor and War Doctor's regenerations respectively. The Eighth Doctor's regeneration into the War Doctor uses steady beams of light as opposed to the flame effect used for other revived series regenerations. In the Series 10 episode "The Lie of the Land", the Twelfth Doctor fakes a regeneration as part of a plan to test if Bill still has free will. The effect used is consistent with the one used in the modern series, with the Doctor's hands glowing and emitting regeneration energy before he enters full regeneration. However, as the regeneration was not real, it did not use up a regeneration and the Doctor did not change bodies.

Question: How much does the person Iron Man showed up at Grand Central Station with weigh? Passage:Doom hires various villains to find the bricks for him, starting with Abomination and Sandman, who hold Grand Central Station at ransom for a Cosmic Brick. Iron Man and Hulk show up at the station, with Spider-Man joining them later on, and together they manage to defeat the two villains, who are subsequently imprisoned in a nearby maximum security prison called the Raft, while Nick Fury leaves the Cosmic Brick in Mister Fantastic's care at the Baxter Building. Mister Fantastic and Captain America arrive at the building shortly after to examine the Cosmic Brick, but find it under attack by Doctor Octopus, who steals the brick and leaves his Octobots behind to keep the heroes busy. After destroying them, Mister Fantastic and Captain America chase after a fleeing Doctor Octopus across several rooftops, with their battle going through the Daily Bugle as well, where Peter Parker, Spider-Man's alter-ego, sees them and suits up as Spider-Man to lend a hand. The three heroes eventually battle Doctor Octopus in Times Square and manage to defeat him, but he tosses the brick to Green Goblin, who takes it to Oscorp. Fury sends Black Widow and Hawkeye to get it back, with Spider-Man joining them later on. They eventually confront Green Goblin in his office, but he opens a trapdoor that sends the heroes to Oscorp's underground lab, where they are forced to fight Venom and his symbiote-infected scientists. Although the heroes defeat Venom, the Goblin escapes with the brick via helicopter.

Question: How many awards did the female writer of the Singin' in the Rain screenplay win in her career? Passage:The film was only a modest hit when first released. O'Connor won the Golden Globe Award for Best Actor Motion Picture Musical or Comedy, and Betty Comden and Adolph Green won the Writers Guild of America Award for their screenplay, while Jean Hagen was nominated for the Academy Award for Best Supporting Actress. However, it has since been accorded legendary status by contemporary critics, and is frequently regarded as the best film musical ever made, and the best film ever made in the "Freed Unit" at Metro-Goldwyn-Mayer. It topped the AFI's Greatest Movie Musicals list and is ranked as the fifth-greatest American motion picture of all time in its updated list of the greatest American films in 2007. In 1989, the United States Library of Congress selected the film for preservation in the National Film Registry. In 2005 the British Film Institute included it in its list of the 50 films to be seen by the age of 14. In Sight & Sound magazine's 2017 list of the 50 greatest films of all time, Singin' in the Rain placed 20th.
