Document 4: Once More, with Feeling (Buffy the Vampire Slayer): All of the regular cast performed their own vocals, although two actors were given minimal singing at their request. ``Once More, with Feeling ''is the most technically complex episode in the series, as extra voice and dance training for the cast was interspersed with the production of four other Buffy episodes. It was Joss Whedon's first attempt at writing music, and different styles -- from 1950s sitcom theme music to rock opera -- express the characters' secrets in specific ways. The episode was well received critically upon airing, specifically for containing the humor and wit to which fans had become accustomed. The musical format allowed characters to stay true to their natures while they struggled to overcome deceit and miscommunication, fitting with the sixth season's themes of growing up and facing adult responsibilities. It is considered one of the most effective and popular episodes of the series, and -- prior to a financial dispute in 2007 -- was shown in theaters with the audience invited to sing along.
Document 5: Thriller (song): Swedien and Jones stated that Vincent Price recorded his introduction and voice - over rap for the song in two takes; Jones, acknowledging that doing a voice - over for a song is ``difficult '', praised Price and described his recording takes as being`` fabulous''. Swedien said of Jackson recording the song, that, ``I tried all sorts of things with Michael -- for instance, he would sing the main vocal part and we'd double it one time and then I'd ask him to step away from the mic and do it a third time and that really changed the acoustics in the room so it gave Michael's vocals a unique character... We recorded some of those background vocals in the shower stall at Westlake. ''
Document 6: Al MacKenzie: Alphonso ``Mack ''Mackenzie appears in the TV series Agents of S.H.I.E.L.D., portrayed by Henry Simmons. He is depicted as an African - American mechanic and engineer who is recruited into the newly rebuilt S.H.I.E.L.D. by Phil Coulson after the events of the film Captain America: The Winter Soldier. He is also old friends with Barbara`` Bobbi'' Morse. In the episode ``One of Us, ''it is revealed that he and Bobbi are secretly associated with`` the real S.H.I.E.L.D.'' led by Robert Gonzales. Later he permanently sides with Coulson. At the time when Inhumans have been emerging in the world, Mack started to develop a relationship with an Inhuman named Elena ``Yo - Yo ''Rodriguez. The episode`` Watchdogs'' introduces Mack's brother Ruben Mackenzie (portrayed by Gaius Charles) who later discovers his brother's job as S.H.I.E.L.D. even at the time when the Watchdogs raid Mack's house upon mistaking him for an Inhuman. In season 4 episode ``Wake Up '', Mack is revealed to be in constant pain due to the loss of his daughter Hope who died as an infant four days after birth due to an unstable and unidentified medical condition. In the episode`` Identity and Change,'' Mack is shown in the Framework to have Hope Mackenzie (portrayed by Jordan Rivera) alive in there. He is forced to leave by Yo - Yo when the Framework begins to fall apart. Simmons reprises his role in a six part web series titled Agents of S.H.I.E.L.D.: Slingshot.
Document 7: Degrassi: Next Class: The opening sequence of ``Next Class ''returned to the longer openings that was featured in the first twelve seasons of`` The Next Generation'' but was cut to 31 seconds. The opening comes after a two - to three - minute cold open but does not follow the characters around the school. Instead, a montage of videos and pictures from the characters social media accounts cycle across the screen. Like the final two seasons of ``Degrassi '', instead of listing every ensemble actor in the opening, episodes only credit the regular actors appearing in that episode. The theme music,`` Whatever It Takes'', was composed by Jim McGrath, with lyrics written by Jody Colero and Stephen Stohn. The lyrics for the theme music for the first four seasons of ``Next Class ''were the same as theme music for`` The Next Generation.'' The ``Next Class ''opening sequence featured a rearranged version of`` Whatever It Takes'' composed by Jody Colero, Jim McGrath, Stephen Stohn, Rob Wells, and Shobha. Shobha also recorded the song.

Document 10: C. J. Cregg: C.J.'s lip - synched performance of ``The Jackal ''by Ronny Jordan in the episode`` Six Meetings Before Lunch'' was written in after Sorkin witnessed Janney doing ``some impromptu lip - synching ''in her trailer on the set.

Document 11: Someone to Watch Over Me (Battlestar Galactica): Alan Sepinwall of The Star - Ledger found that the episode was an excellent showcase for both Katee Sackhoff and Grace Park, and praised director Michael Nankin who ``(infused) this episode with the qualities of a nightmare. ''Michael Saba of Paste Magazine called the episode an`` exercise in building tension through omission'' and felt the episode was ``excellent ''. IGN writer Eric Goldman praised the writers of the show for the plot turns in the episode, in particular the fact that Boomer's returning to the fleet with Ellen Tigh was in fact just a ruse. Goldman felt the subplot involving Kara was`` a bit meandering'' but that Katee Sackhoff and Roark Critchlow gave strong performances. Cinema Blend felt the writers ``threw a neat little curveball ''with the Roark Critchlow piano playing character being Thrace's father. Marc Bernardin of Entertainment Weekly felt the Boomer storyline was`` awesome'' but was less impressed by the storyline involving Thrace, feeling ``that it did n't tell us anything new ''and that the writers had written a very obvious ending to the subplot.
