The mutants of "X-Men" were anything but muted Thursday night.
Director Bryan Singer's "X-Men: Days of Future Past" grossed a studio-estimated $8.1 million in ticket sales from Thursday night showings in 2,900 theaters starting at 10 p.m.
That's a strong start for the $200-million movie, the seventh in the "X-Men" series, which is expected to take in $100 million or more over the four-day Memorial Day weekend in its domestic debut, according to people who've seen pre-release audience surveys.
Last week, the big-budget hit "Godzilla" generated $9.3 million from its Thursday night launch, which started at 7 p.m. That movie went on to gross $93 million in its first three days. "The Amazing Spider-Man 2" debuted with $8.7 million from Thursday night showings that started at 8 p.m. on its way to a $92-million three-day debut.
