Pennywise kept many children up all night in the early 1990s.

But it looks like the evil clown will be back in an even more terrifying form.

A new image of Pennywise from the upcoming remake of Stephen King's It has been released showing the evil character in full garb while flashing a sadistic look into the camera.

Evil incarnate: This image of killer clown Pennywise from the upcoming remake of Stephen King's It was released on Tuesday

It comes just days after the first trailer was shown over the weekend as part of the SXSW Conference And Festivals.

Though no footage has made it on the internet and no one was permitted to record it, Trace Thurman from horror movie site Bloody Disgusting was in attendance to detail the horrifying 90-second clip.

The writer for the publication said that things were so tense in the theater leading up to one scene which left the 'audience screaming.'

Killer clown: The new version of villain Pennywise seems to be as horrifying as ever

It apparently begins with Bill Denbrough (Jaeden Liebherher) making a paper boat for his younger brother Georgie (Jackson Robert Scott).

The youngster is then seen chasing the boat in the middle of the rainstorm as it floats away, he accidentally bumps into a street barrier and watches it as it falls into the gutter.

Thurman writes: 'As he looks deep into the sewers, Pennywise abruptly appears before the screen cuts to black.'

Rising star: Stranger Things star Finn Wolfhard is also one of the stars of the horror film

Also featured in the trailer are the Loser's Club, as they are a group of social misfits who form a tight-knit friendship and will eventually encounter the killer clown. The site continues: 'Realizing that they’ve all been seeing the same entity, before one of them finally says "The Clown."

'Once that happens, the teaser then moves into its centerpiece, which shows the members of the Losers Club looking at pictures on a carousel slide projector that suddenly acquires a life of its own and begins moving through the slides at an increasingly alarming speed.'

According to the writer, the photos are of Georgie and his parents and eventually it zooms in on the mother as her hair is over her face but is revealed to be Pennywise himself.

Original: The original version of It was on the small-screen as a mini-series which aired in 1990

Terrifying: The original clown scared children throughout the early Nineties

Legend: The original Pennywise from the mini-series was played by Tim Curry

The conclusion seems to have the most horrifying moment of the spot as Trace wrote: 'The teaser ends with Bill walking down into his flooded basement, where Georgie's ghost taunts him by repeatedly screaming "We all float down here!" before Pennywise rises from the water and rushes at him, in a moment that had the entire audience screaming.'

Genesis: It is based on the original 1986 novel of the same name written by Stephen King

Playing Pennywise this time around will be hunky actor Bill Skarsgard, best known for his work in Allegiant and Hemlock Grove, but he did not have any speaking parts in the clip.

It is set in a small town in Maine as the motley crew of the Losers Club not only deal with growing up but also face-off with the killer clown.

The original version of It was on the small-screen as a mini-series which aired in 1990 on ABC.

In this iconic version, the clown villain was portrayed by Rocky Horror Picture Show star Tim Curry.

Both adaptations are based on the original 1986 novel of the same name written by Stephen King.

The new feature film is directed by Andrés Muschietti and will feature a very young cast including Stranger Things star Finn Wolfhard, Megan Charpentier, Nicholas Hamilton, Steven Williams, Owen Teague, Wyatt Oleff, and Javier Botet.

It will scare audiences into theaters on September 8 in the US and the UK.
