Premiere for X-Men: First Class.
The premiere for X-Men: First Class happened at the Ziegfeld Theatre in New York City, on May 25, 2011. A week later, on June 3, the film had its wide opening. In North America, the film opened on approximately 6,900 screens at 3,641 locations, debuting atop the weekend box office with earnings of $55.1 million across the three days, including $3.37 million at its Friday midnight launch. This opening was much lower than the opening weekends of X-Men: The Last Stand ($102.7 million), X2: X-Men United ($85.5 million), and X-Men Origins: Wolverine ($85.0 million), but it was slightly higher than X-Men ($54.5 million). Executives at 20th Century Fox said they achieved their goal by opening with about the same numbers as the first X-Men film and that it was an excellent start to a new chapter of the franchise. First Class also opened 8,900 locations in 74 overseas markets, which brought in $61 million during the weekend—standing third in the overseas ranking behind Pirates of the Caribbean: On Stranger Tides and The Hangover Part II. The film opened atop the box office in twenty countries, with the biggest grosses being in the United Kingdom ($9 million, including previews), France ($7.1 million), Mexico ($5 million), South Korea ($5.4 million ) and Australia ($5.1 million). In its second weekend X-Men: First Class dropped 56.2%, the second smallest second weekend drop in the franchise behind X-2: X-Men United (53.2%), and came in with an estimated $24.1 million, in second place to Super 8. Overseas, it raised to number two behind Kung Fu Panda 2, with $42.2 million.
The film grossed $146,408,305 in the United States and Canada as well as $207,215,819 internationally, bringing its worldwide total to $353,624,124.
