20th Century Fox rolled out its superhero prequel X-Men: First Class at midnight, taking in an estimated $3.4 million from those late showings. That number is just slightly ahead of Marvel's Thor, which earned $3.3 million in midnight screenings nearly one month ago.

It isn't known how many screens X-Men: First Class played in at midnight last night, although it opens in 3,641 theaters nationwide starting today. Some have tracked X-Men: First Class earnings at between $48 and $55 million this weekend, while others believe it could gross north of $60 million. Since X-Men: First Class took in slightly more than Thor at midnight, it may very well replicate Thor's $65.7 million opening weekend, or come close to it.
