Arguably the most memorable sequence in 2014's X-Men: Days of Future Past was "the Quicksilver scene," where the speedster mutant aided Wolverine and Charles Xavier in their mission to break Magneto out of the Pentagon. Using his powers, Quicksilver immediately turned the odds in his new friends' favor and became an instant hit with moviegoers everywhere. Those concerns about his appearance seemed silly after the fact.

Quicksilver was such a success that director Bryan Singer had no choice but to bring the character back for this summer's X-Men: Apocalypse, and actor Evan Peters is ready to top his previous outing. It's long been reported that the special Quicksilver-centric sequence in Apocalypse is far larger than the one shown in Days of Future Past (which wasn't exactly small scale). Now, Singer himself has revealed just how long his team worked on it to make sure they got it all right.

In an Instagram post, the filmmaker thanked 20th Century Fox for securing a television spot for Apocalypse during the Super Bowl 50 broadcast on CBS. He shared a screenshot of the ad, showing Quicksilver running through a hallway (which has also been featured in the trailer), expressing gratitude for the amount of effort that went into filming the scene:

You can have fast or cute. Thank you @20thcenturyfox marketing #marcweinstock #davesingh #elyorias and the team for getting us on #superbowl50 #nfl #fox#football #XMen #xmenapocalypse FYI this scene with #evanpeters as #quicksilver took one and a half months for a less than 3 minute sequence resulting in Evan working longer than any other actor on the film. Thanks Evan and #ryanmurphy @ahsfx for accommodating! A photo posted by Bryan Singer (@bryanjaysinger) on

It is insane to consider that it took that many days to shoot it all, especially when compared to the one from Days of Future Past. The Pentagon scene was a late addition to that film, and all of the slow-motion scenes were shot during the final two days of the project. To go from a couple of days to over a month is quite an increase, illustrating that this is indeed a far more intricate sequence than fans may have been prepared for. It calls into question why exactly so much more time was needed.

As challenging as it was to film, the Days of Future Past sequence was confined to a relatively small area, the Pentagon cafeteria. Based on the Apocalypse footage that's been shown so far, it's safe to say that the new Quicksilver scene takes place in a far more open area. It conceivably could be Xavier's School for Gifted Youngsters or some other large building (again, the hallway), requiring Singer's team to film in multiple locations with the complex setup involving phantom cameras and lights. Normal action sequences can take a while to shoot, but this one heavily relies on visual effects, particularly the slow-mo elements to depict Quicksilver's powers.

Whether it's fair or not, fans will no doubt be comparing the two scenes once Apocalypse reaches theaters. It's most likely for this reason Singer went all out to craft something even more extraordinary. Expectations for Quicksilver are now through the roof after he stole the show in Days of Future Past, and viewers want to see an evolution of his powers in the next film. Even if the Apocalypse scene were on the same level as its predecessor (in terms of the shooting schedule), that could be a disappointment to some. When we visited the Apocalypse set last summer, Peters actually compared it to a sequel, where the old adage usually is bigger is better.

Time will tell just how memorable Quicksilver's latest exploits are, but one can't say the Apocalypse team didn't try. There was obviously a lot of planning and work put into it, and fans can certainly appreciate that level of dedication. It's rare nowadays when a big action sequence blows the collective minds of the audience, but Days of Future Past managed to do just that. Apocalypse has a tough act to follow, but it sounds like it just might pull it off.
