Question: Kang Sung-yeon played Prince Yeonsan in a film that runs for how many minutes ?

Context:
Yeonsangun of Joseon
Yeonsan-gun or Prince Yeonsan (23 November 1476 – 20 November 1506, r. 1494–1506), born Yi Yung or Lee Yoong, was the 10th king of Korea's Joseon Dynasty.
 He was the eldest son of Seongjong by his second wife, Lady Yoon.
 He is often considered the worst tyrant of the Joseon Dynasty, notorious for launching two bloody purges of the seonbi elite.
 He also seized a thousand women from the provinces to serve as palace entertainers, and appropriated the Seonggyungwan study hall as a personal pleasure ground.
 Overthrown, Yeonsan-gun did not receive a temple name.
Surrogate model
A surrogate model is an engineering method used when an outcome of interest cannot be easily directly measured, so a model of the outcome is used instead.
 Most engineering design problems require experiments and/or simulations to evaluate design objective and constraint functions as function of design variables.
 For example, in order to find the optimal airfoil shape for an aircraft wing, an engineer simulates the air flow around the wing for different shape variables (length, curvature, material, .
.)
.
 For many real world problems, however, a single simulation can take many minutes, hours, or even days to complete.
 As a result, routine tasks such as design optimization, design space exploration, sensitivity analysis and "what-if" analysis become impossible since they require thousands or even millions of simulation evaluations.

Broadpoint
BroadPoint Communications was a US telecommunications company in the late 1990s offering free long-distance calling supported by advertising, a service the company called "Sponsored Communications."
 Perry Kamel was founder and CEO of the company, based in Landover, Maryland.
 Users would sign up online for the company's FreeWay service by filling out a questionnaire.
 To make calls, users dialed the BroadPoint toll-free number, then entered their PIN, followed by the desired number.
 Users could then earn minutes of calling time by listening to brief advertisements, five to fifteen seconds in length, targeted to their interests and location.
 GEICO was a frequent advertiser.
 However, the minutes earned could not be carried over to another call, so users would sometimes accrue many minutes of free calling, only to lose them when their intended party was busy or did not answer.
 Perhaps because of such shortcomings, the FreeWay service soon ended.
 The company filed for Chapter 7 liquidation in January 2002.
 Broadpoint's former URL is no longer associated with the company, and is now made up only of advertising links.
 Kamel went on to become CEO of Maxamine, a Web analysis company, and is now CEO of Elateral, which describes itself as a "global branding, marketing and design consultancy."
