Helloween are a German power metal band founded in 1984 in Hamburg, Northern Germany by members of bands Iron Fist and Gentry. Its first line-up consisted of singer and rhythm guitarist Kai Hansen, bass guitarist Markus Grosskopf, lead guitarist Michael Weikath, and drummer Ingo Schwichtenberg. After the release of a self-titled EP and their debut album Walls of Jericho in 1985, it expanded into a quintet with the addition of singer Michael Kiske, Hansen choosing to focus on guitar instead. Under this line-up, they released the Keeper of the Seven Keys albums (1987 and 1988), which established Helloween as a notable heavy metal band and led to the creation of the power metal subgenre.
The year 2000 saw the release of The Dark Ride, a more experimental and darker album than their previous releases. It came complete with downtuned guitars and a gruffer singing style from Deris. Immediately following the tour, Helloween parted ways with guitarist Roland Grapow and drummer Uli Kusch. One version of events states that Weikath, Deris, and Grosskopf felt that Kusch and Grapow, in particular, were spending more time on and paying more attention to their new side-project, Masterplan (Grapow's output on Helloween albums had dropped to barely one song per album by that point); since the others believed that Kusch and Grapow were not one hundred percent dedicated to Helloween, they were dismissed.  They were replaced by guitarist Sascha Gerstner (ex-Freedom Call, Neumond) and drummer Mark Cross (ex-Metalium, Kingdom Come, At Vance, Firewind), culminating with the recording of another studio album, titled Rabbit Don't Come Easy, in 2003. The band met Sascha via a recommendation by producer Charlie Bauerfeind. According to Grosskopf, one day he was recording something with Freedom Call "and later on we called him up and he went to first meet Weiki because it was very important that Weiki finds a player that he can play with and also communicate and understand. [...] So we got him on the island where we recorded and let him hang out with us a little and then he decided 'Good, let's go'." Later in 2012, on an interview with Metal Shock Finland's Chief Editor, Mohsen Fayyazi, Roland stated:  Cross could not finish the album due to mononucleosis, completing only two tracks; the drum tracks were completed by Motorhead's Mikkey Dee. Stefan Schwarzmann, former drummer of Running Wild and Accept would shortly thereafter take over the drumming duties. Despite a somewhat tepid response to the album, Helloween nonetheless completed a successful world tour, highlighted by the return of classic songs such as "Starlight", "Murderer", "Keeper of the Seven Keys" and "How Many Tears" to the setlist. Additionally, the band toured the United States for the first time since 1989, playing to sold-out crowds at nearly every venue.

Was there tension between the members of the band?

Weikath, Deris, and Grosskopf felt that Kusch and Grapow, in particular, were spending more time on and paying more attention to their new side-project, Masterplan

Zelig is a 1983 American mockumentary film written and directed by Woody Allen and starring Allen and Mia Farrow. Allen plays Leonard Zelig, a nondescript enigma, who, out of his desire to fit in and be liked, takes on the characteristics of strong personalities around him. The film, presented as a documentary, recounts his intense period of celebrity in the 1920s and includes analyses from contemporary intellectuals. Zelig was photographed and narrated in the style of 1920s black-and-white newsreels, which are interwoven with archival footage from the era and re-enactments of real historical events.
Zelig has an overall approval rating of 100% on the review aggregator Rotten Tomatoes based on reviews from 24 professional critics with an average score of 7.9/10. In his review in the New York Times, Vincent Canby observed:  [Allen's] new, remarkably self-assured comedy is to his career what ... Berlin Alexanderplatz is to Rainer Werner Fassbinder's and ... Fanny and Alexander is to Ingmar Bergman's ... Zelig is not only pricelessly funny, it's also, on occasion, very moving. It works simultaneously as social history, as a love story, as an examination of several different kinds of film narrative, as satire and as parody ... [It] is a nearly perfect - and perfectly original - Woody Allen comedy.  Variety said the film was "consistently funny, though more academic than boulevardier", and the Christian Science Monitor called it "amazingly funny and poignant". Time Out described it as "a strong contender for Allen's most fascinating film", while TV Guide said, "Allen's ongoing struggles with psychoanalysis and his Jewish identity - stridently literal preoccupations in most of his work - are for once rendered allegorically. The result is deeply satisfying".  In Empire magazine's poll of the 500 greatest movies ever made, Zelig was ranked number 408. Chris Nashawaty of Entertainment Weekly listed the work as one of Allen's finest, lauding it as "a spot-on homage to vintage newsreels and a seamless exercise in technique." The Daily Telegraph film critics Robbie Collin and Tim Robey also named it as a career highlight and argued, "The special effects, in which Allen is seamlessly inserted into vintage newsreels, are still astonishing, and draw out the aching tragicomedy of Zelig's plight. He's the original man who wasn't there." Calum Marsh of Slant magazine wrote, "We are infinitely pliable. That's the thesis of Zelig, Allen's wisest film, which has much to say about the way a person can be bent and contorted in the name of acceptance. Its ostensibly wacky conceit [...] is grounded in an emotional and psychological reality all too familiar to shrug of [sic] as farce. We'll go very far out of our way to avoid conflict. Zelig seizes on that weakness and forces us to recognize it."
