Christopher Markus (born October 16, 1969) and Stephen McFeely (born February 24, 1970) are American screenwriters and producers. McFeely and Markus were the second and the third most successful screenwriters of all time in terms of U.S. box office receipts with a shared total gross of over $3.1 billion. However, in overall, they are the highest grossing screenwriters altogether in terms of worldwide box office with the total gross of $9.3 billion. They gained worldwide recognition for their works that include The Chronicles of Narnia film franchise and the Marvel Cinematic Universe (MCU), having written the first three Captain America films (The First Avenger, The Winter Soldier and Civil War), in addition to Thor: The Dark World, Avengers: Infinity War, and Avengers: Endgame, which is currently the second highest-grossing film of all time unadjusted for inflation. They also created ABC's Agent Carter TV series, set in the MCU.

Most of the X-Men are mutants, a subspecies of humans who are born with superhuman abilities activated by the "X-Gene". The X-Men fight for peace and equality between normal humans and mutants in a world where anti-mutant bigotry is fierce and widespread. They are led by Charles Xavier, also known as Professor X, a powerful mutant telepath who can control and read minds. Their archenemy is Magneto, a powerful mutant with the ability to manipulate and control magnetic fields who leads the Brotherhood of Mutants. Both have opposing views and philosophies regarding the relationship between mutants and humans. While the former works towards peace and understanding between mutants and humans, the latter views humans as a threat and believes in taking an aggressive approach against them, though he has found himself working alongside the X-Men from time to time.
