The marketing campaign is well and truly underway for Joss Whedon’s upcoming The Avengers, which brings together all of the awesome characters we’ve loved watching over the past few years in their separate movies for one epic superhero blockbuster.

Just last night, we put up some great images and specs of Tony Stark’s $9m. car that’s on display at Sundance to promote the film, and today we’ve got more brilliant stills to share with you. Marvel have released five hi-res stills, with thanks to ComicBookMovie.com for the tip-off, three of which we’ve seen before just a few days ago, but only as scans from Empire Magazine.

We also heard talk yesterday about the possibility of Captain America 2 going into production this year following Iron Man 3 and Thor 2, as well as the S.H.I.E.L.D. movie potentially following those three. Marvel are certainly firing on all cylinders, and doing one hell of a job at it too.

Whedon is directing The Avengers from a script he’s co-written with Zak Penn (X-Men: The Last Stand, The Incredible Hulk), and all of our favourite superhero cast from the Marvel Universe will of course be reprising their roles from recent years, including Iron Man (Robert Downey, Jr., with Paul Bettany returning as JARVIS), Thor (Chris Hemsworth), Captain America (Chris Evans), the Hulk (Mark Ruffalo, taking over from Edward Norton), Hawkeye (Jeremy Renner), Black Widow (Scarlet Johansson), Nick Fury (Samuel L. Jackson), Agent Coulson (Clark Gregg), Pepper Potts (Gwyneth Paltrow), and Loki (Tom Hiddleston).

The Avengers will be released here in the UK in 3D on 27th April, precisely three months from today. Anybody else excited? (As if I even need to ask.) You can catch up on all things The Avengers-related right here, and if you’ve not yet seen it but would like to, I’ll particularly point your attention towards the rather impressive (read: utterly incredible) first trailer that surfaced late last year. And as usual with these new images, you can click to enlarge. I especially love the second one of Samuel L. Jackson/Nick Fury at the head of the table, staring down the camera. And Jeremy Renner’s veins look a little bit like they’re about to explode in the fourth shot. Awesome stuff.
