A new teaser was released for horror flick Longlegs - which is said to be 'psychologically scarring' - on Monday as it showed that Maika's, 31, heart rate spiked as she saw what 60-year-old Nicholas' character looked like for the first time.
The minute-long clip was the latest in a creative promotional push for the Neon produced film as it began with words flashing across the screen which gave the premise for the video.
It read: 'The first time Maika Monroe saw Nicolas Cage as Longlegs was in the following scene.
'What you're about o hear is Maika's actual heartbeat.'

'What you're about o hear is Maika's actual heartbeat'
Maika is then seen in character as Agent Lee Harker as she stands in the hallway outside of a door.
Her heartbeat could be heard going at normal rate when writer and director Oz Perkins could be heard calling 'action.'
Maika then opens the door and her heartbeat could be heard going at a considerably faster pace.
Things ramp up even more as Nicolas could be heard whimpering as she approaches him.
She then sits across from him as her heart rate jumps exponentially and tears begin running down her face.
There is still quite a bit of mystery regarding what Nicolas' titular character looks like as his face is entirely censored.
The end of the clip revealed the shocking statistics as it read: 'Maika's resting heart rate is 76bpm.
'In this scene, it hit 170bpm.'

One person on LetterBoxd wrote: 'Longlegs is a scary movie. But not scary, like cue the loud music, cut to scary ghoul, audience gasps, movie continues... Longlegs is scary in the way that it crawls under your skin and gnaws at your bones.
'It's the festering wound in a spot you can't reach. A movie that reminds you that evil exists.'
Another commented: 'Unlike so much mainstream horror, Longlegs refuses to hold your hand.
'It's a chilling amalgamation of a Fincher-esque procedural with classic religious fanaticism, and the result is something uniquely nightmarish.
'It's difficult to iterate how good Maika Monroe and Nicolas Cage are. Their performances are more of an experience - something for the horror history books.
'Admittedly, this type of movie is my love language, but it's been a minute since a serial killer horror movie has been this good. All praise [director] Oz Perkins.'
Someone else quipped: 'My favorite part was when I was able to exit the theater into broad daylight and a happy crowded street.'
But the praise did not stop there as another viewer shared: 'LONGLEGS is one of the best serial killer films in recent memory.

The movie, which also casts Nicolas Cage, 60, will be released on July 12 but is already being hailed as 'sinister' and 'unsettling' by early viewers
Horror movie fans have been sent into a frenzy over the 'psychologically scarring' new flick - and it has already earned a 100 per cent rating on Rotten Tomatoes
'The confidence Oz Perkins displays in his framing, atmosphere, and pacing, has been suggested before, but it reaches its full potential in this psychologically scarring police procedural, that steadily evolves into something even more sinister and otherworldly.
'Maika Monroe and Nicolas Cage are phenomenal with the former barely keeping it together under intense emotional distress, while the latter delivers a disturbing, but controlled performance that stays consistent with Perkins' chilling tone.
'A meticulously crafted and unnerving descent into hell that will haunt your mind and soul.'

Director Oz Perkins previously shared with IndieWire: 'I'm somewhat surprised that people are so kind of terrified by it and find it to be so intense and so gnarly and so grotesque and so brutal.
'I never set out to make anybody feel bad.
'I don't know that any filmmaker necessarily does, although there's a couple of people who wonder if their intention is to make people feel bad.
'I don't like those movies at all. But for me, honestly, I just tried to make something that was good and that people would want to enjoy.'
