The latest X-Men offering is expected to take the box office by storm this weekend, as the mutant superhero gang reunites for one of the biggest US film-going holidays of the year.
X-Men: Days of Future Past, a time-bending movie that is already a hit with critics, could make up to $110 million.
The film, in which Hugh Jackman's saber-knuckled Wolverine travels back in time to save the earth from a devastating war, could become one of the biggest grossing movies of all time, according to industry journal Variety.
Review website Rotten Tomatoes gave it a huge 91 percent approval rating, saying it "combines the best elements of the series to produce a satisfyingly fast-paced outing that ranks among the franchise's finest installments".

The star-studded cast including Ian McKellen, Patrick Stewart, Michael Fassbender and Halle Berry probably won't hurt the bottom line either.
It features three Oscar-winning actresses Halle Berry, Jennifer Lawrence and Anna Paquin, and multiple Academy Award nominees including McKellen, Jackman and Fassbender.
"The reviews have been great and we're confident that everyone, X-fans and non-X-fans, will see this movie and really like it," Chris Aronson, president of domestic distribution at 20th Century Fox, told Variety.
It opened Thursday in many countries around the world.
A big opening for X-Men would continue a solid run this year for films starring characters from the Marvel Comics universe.
Sequel Captain America: The Winter Soldier led the North American box office for three weeks in April, and The Amazing Spider-Man 2 opened in the top spot earlier this month.
