Question: What category do the films Beyond the Call and Without the King fall into?
Context: In software, a stack overflow occurs if the call stack pointer exceeds the stack bound.  The call stack may consist of a limited amount of address space, often determined at the start of the program.  The size of the call stack depends on many factors, including the programming language, machine architecture, multi-threading, and amount of available memory.  When a program attempts to use more space than is available on the call stack (that is, when it attempts to access memory beyond the call stack's bounds, which is essentially a buffer overflow), the stack is said to "overflow", typically resulting in a program crash. I Get This Call Every Day is a point-and-click video game developed, programmed, and published by Toronto-based developer David S Gallant.  It was released for Microsoft Windows and OS X on December 21, 2012.  It focuses on a call received by an employee of a customer service call centre; the player must navigate through the call without irritating the caller or breaking confidentiality laws.  Gallant was fired from his job at a call centre as a direct result of publishing the game. Fall Out Boy's Evening Out with Your Girlfriend is the debut mini-LP by American rock band Fall Out Boy.  Recorded in two days around February to September 2002 on a low budget, the rushed schedule left the band discontent and ceasing to call it their debut album.  "Fall Out Boy's Evening Out with Your Girlfriend" was released in 2003 through Uprising Records against the band's wishes.  In 2005, Uprising released a remastered reissue as Evening Out with Your Girlfriend, without the band's involvement, following the band's very successful major label debut "From Under the Cork Tree".  It eventually sold over 127,000 copies in the United States by August 2008, according to "Billboard".  The photograph on the cover of this album was shot by Adeet Deshmukh in Chicago's Pick Me Up Café located at 3408 N. Clark Street.  The girl who is pictured on the cover is a waitress at said café, and her name is Lavinia, as noted in the booklet of the album. Without the King is a 2007 documentary film by Michael Skolnik, an American filmmaker.  It follows problems of Swaziland, a landlocked country in southern Africa. Wheel alignment, sometimes referred to as breaking or tracking, is part of standard automobile maintenance that consists of adjusting the angles of wheels so that they are parallel to each other and perpendicular to the ground.  The purpose of these adjustments is to reduce tire wear, and to ensure that vehicle travel is straight and true (without "pulling" to one side).  Alignment angles can also be altered beyond the maker's specifications to obtain a specific handling characteristic.  Motorsport and off-road applications may call for angles to be adjusted well beyond "normal", for a variety of reasons. Beyond the Fall of Night (1990) is a novel by Arthur C. Clarke and Gregory Benford.  The first part of "Beyond the Fall of Night" is a reprint of Clarke’s "Against the Fall of Night" while the second half is a "sequel" by Gregory Benford that takes place many years later.  This book is unrelated to "The City and the Stars" which is an expanded version of "Against the Fall of Night" which Clarke wrote himself three years after the publication of "Against the Fall of Night". Agent-assisted automation is a type of call center technology that automates elements of what the call center agent 1) does with his/her desktop tools and/or 2) says to customers during the call using pre-recorded audio.  It is a relatively new category of call center technology that shows promise in improving call center productivity and compliance. Beyond the Call is a 2006 documentary film about three middle-aged men who are former soldiers and modern-day knights.  They travel the world delivering life saving humanitarian aid directly into the hands of civilians and doctors in some of the most dangerous yet beautiful places on Earth, the front lines of war.  It is the directorial debut of Academy Award nominee Adrian Belic.  The film has been screened in over 80 film festivals on five continents, winning 25 awards so far. A collect call in Canada, Pakistan, and the United States, also known as a reverse charge call in other parts of the English-speaking world, is a telephone call in which the calling party wants to place a call at the called party's expense.  In the past, collect calls were only possible as an operator-assisted call, but with the introduction of computer-based telephone dialing equipment, it is now possible to place a collect call without using an operator, which is called automated operator services (AOS) as opposed to Home Country Direct (HCD).  Several companies offer services to place collect calls that compete with local service providers.  Collect calls can be made from almost any public pay telephone in the world by following directions posted on or near the phone.  Collect calling has been in constant decline since the advent of cellular phones and VOIP products, which can offer cheaper international rates. In mathematics, an abelian category is a category in which morphisms and objects can be added and in which kernels and cokernels exist and have desirable properties.  The motivating prototype example of an abelian category is the category of abelian groups, Ab.  The theory originated in an effort to unify several cohomology theories by Alexander Grothendieck and independently in the slightly earlier work of David Buchsbaum.  Abelian categories are very "stable" categories, for example they are regular and they satisfy the snake lemma.  The class of Abelian categories is closed under several categorical constructions, for example, the category of chain complexes of an Abelian category, or the category of functors from a small category to an Abelian category are Abelian as well.  These stability properties make them inevitable in homological algebra and beyond; the theory has major applications in algebraic geometry, cohomology and pure category theory.  Abelian categories are named after Niels Henrik Abel.
