You know when a trailer gets its own trailer that the film it's promoting is something to look forward to.

After three days of build-up with short teasers offering plenty of glimpses of the end product, the first official trailer for Ridley Scott's 'Alien' prequel 'Prometheus' is finally here.

Once upon a time (six months ago) the film wasn't even supposed to be an 'Alien' prequel at all, but, as we'd all suspected, it turns out Scott was telling fibs.

The claim now is that 'Prometheus' will share similar DNA with his original 'Alien' film and the trailer definitely confirms that, as well as showing us that without a doubt this is a prequel to the much-loved franchise.

Confirmation comes with the shot of the room from the original film where we first see the Space Jockey, and another shot of the crew of 'Prometheus' (the name of their ship) inspecting what looks a lot like the Space Jockey's head.

It's been a long-time coming, but finally the teaser trailer for 'The Hobbit: An Expected Journey' - the first in a two-part movie adaptation of the Tolkien story, has arrived.

Check out the 'Hobbit' trailer below.

Five things we noticed about 'The Hobbit: An Unexpected Journey' trailer

1) It looks and sounds awfully familiar, and we love it!

The very first scene in the trailer - a prologue that sees Elijah Wood and Sir Ian Holm reprise their roles as Frodo and Bilbo - immediately brings back that 'Lord Of The Rings' feel. From the Hobbiton countryside, the insides of Bag End and the lush Rivendell set, Jackson and his production designers haven't strayed at all from the earlier films. Same with the music: Howard Shore's familiar LOTR score plays from the start.

2) Lots more Gandalf the Grey

It's great to see Sir Ian McKellen back as the fresh-faced (relatively speaking) Gandalf the Grey, rather than the moody and fatalistic 'White' iteration from the 'Rings' sequels. McKellen once said: "Grey Gandalf is my favourite… because he got down and dirty. He slept in the hedgerows; he was closer to the earth and not quite so spiritual. He's also funnier — he's got more variety to him." The wizard is in the trailer a lot - he even has a fight scene - and alongside Martin Freeman's Bilbo he'll surely have the most screen time in 'The Hobbit'.

3) Martin Freeman is perfectly cast

Speaking of which, this is also the first time fans have seen Martin Freeman as Bilbo (most famous as Tim from 'The Office' of course). When he was first announced as the younger version, the vast majority of fans reckoned it was perfect casting and there's nothing to dispel that here. We see Bilbo riding a pony, running with a map, finding ace sword 'Sting' and generally being bumbling and bemused. As he should be.

4) It will be funnier

'The Hobbit' book was much more light hearted and whimsical than the epic and serious 'Lord of the Rings' series, which is reflected in the physical comedy seen in the trailer. We have fat Bofur smashing a chair, the dwarfs falling through a door and what looks like a food fight. Despite the familiar setting, it seems the film makers are striving for a lighter tone this time round. As well they should, 'The Hobbit' is a children's book after all.

5) It's heavily connected to 'The Lord of the Rings'

When it was first green lit, we heard the film makers would use additional story from 'The Lord of the Rings' appendixes to make the second 'Hobbit' a 'bridge' to the 'LOTR' films. It seems from the trailer however that Jackson has also used these elements for 'Part 1' as well. We see Galadriel (Cate Blanchett) - who was not in the book - as well as Frodo and the older Bilbo. McKellen said in an interview that Gandalf's mission to Mirkwood, and his attempts to get the White Council to attack The Necromancer (Sauron), would also be included at some point.

The 'Hobbit' movies: The back-story

A decade ago director Peter Jackson sent people on an epic journey to middle earth when he released the first part of 'The Lord of the Rings'.

It became the kind of cinematic phenomenon that had been sorely lacking since the original 'Star Wars' trilogy came to an end in the late 80s.

Tat's life... Rooney Mara and Daniel Craig in 'Dragon Tattoo'
Even though it's an enormous Hollywood blockbuster based on a bestselling book, most of the pre-publicity chatter around 'The Girl with the Dragon Tattoo' has centered on Rooney Mara and her piercings.

As we now know, the fearless actress had a variety of body parts impaled for the film, including her nipple.

When Yahoo! Movies had a chat with Mara, alongside co-star and Daniel Craig, she admitted she was looking forward to having some of them removed.

"I'm probably going to take out my piercings! But I might keep a few of them, I don't know…"

Meanwhile Craig, happy to be off 'Bond' duty, said it was seeing the book constantly in airports that made him take the role.

"It was difficult to avoid it!" he said. "You'd pass through airports and you'd see ten, twenty people reading copies of the book. What was fascinating was that it was a complete range of ages — from teenagers to old people — it
