The mansion that Deadpool goes to in order to recruit Colossus and Negasonic probably looked familiar. It’s located at the Hatley Park National Historic Site in British Columbia and is the same one used for the home of Lex Luthor in “Smallville,” as well as Oliver Queen’s former home on “Arrow.” In this movie, Deadpool approaches from the opposite side as usually shown in “X-Men” movies, meaning you got a strong sense of deja vu.
