The 'Transformers 4' script may have been leaked. Curious?

I'm always hesitant to post supposedly leaked story scripts or things of that nature, because more often than not they tend to be completely made up. Or they're old, tossed aside versions of the script that are no longer relevant, and thus useless. But in this case I'll take a stab at it because, well, it's Transformers 4. And who doesn't want to know what the heck Michael Bay may be planning on blowing up next?

The apparent leak was made public by Unleash the Fanboy, acquired from some inside source who is so afraid of losing his job that he....leaked the script to a random site like Unleash the Fanboy. Yeah, ok. Anyway, there be some pretty major spoilers ahead, so read on at your own peril.

So I'm just going to re-post everything that seemed relevant to me, and then comment after. Got it? Cool. Read on...

The script begins 4 years after DARK OF THE MOON, in the midst of yet another destructive meteor storm. The opening is very much like the other films, with a generic “crisis montage”.  All the major news networks are scrambling to cover the event, fearing that another alien attack is on its way.
Cut to a giant metal space ball, hurtling through the atmosphere, landing right beside Stonehenge. It creates a cylindrical portal and launches an unseen entity into another dimension. As you can imagine, this agitates pretty much everyone, and the Autobots assemble to figure out what the hell is going on.

Eventually we discover that this giant ball is actually a space ship, designed by an ancient Autobot known as Vector Prime. He’s the guardian of Primus, the one being in the universe that can defeat the planet eating Transformer, and main villain, Unicron. So, Optimus and a handful of Autobots have a grand ol’ time hanging out with Vector Prime, trying to locate Primus.
Meanwhile, Unicron’s flunkies, led by Galvatron, attack a super secret government base in Colorado. 

This place is important for two reasons
1) It houses Decepticon Corpses (including Megatron)
2) It’s the home of a brand new array of Cybertronian-Earth weapons and armor suits. Imagine Iron Man, but sexier and crazier.
Anyway, Galvatron destroys the installation, plugs into the Decepticon bodies in order to download their memories, and in the process he becomes possessed by Megatron. Yeah… that guy’s back in action.
Oh… and when the base is completely destroyed, one human character (Josie/Circuit Breaker) crawls to safety, but in order to survive, she initiates some weird robotic surgery, and transforms herself into a kickass cyborg.
As you’d expect, there are a handful of other human characters tossed into the mix. There’s a Special Ops Sergeant (Beller) who seems perfectly crafted for Mark Wahlberg, a few reckless kids (Beller’s teenage daughter and her race car driving boyfriend) in the style of Shia Labouf and Megan Fox, but sadly no John Turturro cameo.
I don’t want to bore you with the nitty bitty parts of the script, even though there are a fair share of interesting points before it concludes. Here are the bullet points:

• Optimus, Vector Prime, and a handful of Autobouts travel to Mount St. Hellen on the day of its eruption in order to retrieve Primus from Space & Time… or at least I think that’s what they’ve done. Galvatron/Megatron attacks them, revealing himself to Optimus, and craziness unfolds
• They return to the present in order to defend the portal at Stonehenge against Megatron and his Unicron flunkies, in an attempt to survive long enough to ensure Primus’s return
• Josie/Circuit Breaker goes on a wild binge of Transformer murders, unable to distinguish between Autobots and Decepticons because she’s so damn pissed off, having almost been killed.
• Eventually Josie joins forces with the Autobots.
• As the climatic battle unfolds, with Unicron drawing closer to Earth, a group of Dinobots jump through the portal to assist Optimus. Yeah, I said it… DINOBOTS!
• Unicron arrives, transforming the planet into a mechanical sphere reminscent of Cybertron, but he never gets a chance to finish.
• Primus finally makes his debut. He defeats Unicron, kicks that baddie’s soul out of his gigantic metal body, and creates a new planet out of the corpse, perfectly fit for the Autobots.
• In the midst of Unicron’s defeat, Optimus kills Megatron/Galvatron, and all ends well. Kinda. The closing shot reveals Galvatron’s secluded ship, hovering in space, with two bright red eyes shining from within. DUN DUN DUN!

Ok, so this could all be a load of bunk, but there are some interesting things of note. First, it does begin with the film taking place a few years after Dark of the Moon, which is something we learned previously. It also sets up a character for Mark Wahlberg, who came aboard in early November, plenty of time for the script to be updated with a part just for him. The site notes that this version of the story was dated 11/30. There's also room for the two "reckless teens", likely the ones to be played by the newly signed Nicola Peltz and Brenton Thwaites. Other than the stuff with the Dinobots, Unicron, Vector Prime, and Primus, the most surprising aspect is the inclusion of Josie/Circuit Breaker as the real female lead. She was sort of a controversial figure amongst the Transformers fan base, but she could make for an interesting character to lead future films.

So, let's assume this all true for now. Dinobots...Unicron...and Cybertron!!!!!!!! Fanboy overload!! Must refuel, where's my Energon? This could be awesome. Expect to learn more about the veracity of this script very very soon.
